The Role of Industrial Diaphragm Seals

The Role of Industrial Diaphragm Seals

Diaphragm seals protect industrial pressure gauges, transmitters, and other instruments in corrosive, high-temperature, and high-vibration applications for the following reasons:
  1. Protection against corrosive media: Diaphragm seals isolate the gauge from corrosive liquids and gases, preventing damage to the indicator and ensuring accurate readings.
  2. High-temperature resistance: Diaphragm seals use materials that can withstand high temperatures, such as PTFE and Monel, allowing the application of the gauge in high-temperature applications without affecting accuracy.
  3. Vibration resistance: In high-vibration applications, diaphragm seals reduce the vibration transfer to the gauge, reducing the risk of damage and ensuring accuracy.
  4. Media compatibility: The diaphragm material can be selected based on compatibility with the process media, ensuring accurate readings and preventing damage to the gauge.
  5. Longer service life: A diaphragm seal with a pressure gauge in corrosive, high-temperature, and high-vibration applications can extend the service life of the pressure gauge, reducing the need for maintenance and replacements.
Diaphragm seals transfer movement to pressure sensors through mechanical means. A flexible diaphragm is attached to the gauge's sensor and is separated from the process fluid by a filled chamber or a static pressure-transmitting liquid. As the process pressure changes, it causes the diaphragm to flex and transfer the movement to the gauge's sensor, which translates to the pressure reading.

Industrial diaphragm seals provide the "wetted" interface. Wetted refers to the parts of a diaphragm seal that come into contact with the measured process fluid. In industrial diaphragm seals, the wetted components consist of the diaphragm and the metal or ceramic components surrounding the diaphragm and are in direct contact with the process fluid. These parts must be compatible with the process media and withstand the fluid's corrosive and abrasive properties.

In conclusion, diaphragm seals provide a protective interface between the process media and the pressure gauge that ensures protection, accuracy, and increased longevity in challenging industrial applications, making them essential for industrial pressure gauges.

Benefits of Removable Reusable Insulation

Benefits of Removable Reusable Industrial Insulation

Unlike traditional insulation which is only used one time and then disposed, industrial reusable blanket insulation can be used multiple times and therefore it is more cost-effective over time. It can be also used to insulate equipment, valves, pipes, and ducts, as well as the walls, roof, and floor of a building. Additionally, it can be used as heat and fire barriers in certain situations.

Industrial reusable insulation refers to insulation material that is designed for use in industrial settings such as manufacturing facilities, power plants, and other heavy industrial buildings. It is typically made of durable materials such as fiberglass, ceramic, or mineral wool, which can withstand the harsh conditions of an industrial environment. Reusable insulation can be cut to fit any shape or size, making it easy to use in a variety of industrial applications.

Overall, industrial reusable insulation products are designed to help industrial facilities save energy, reduce costs, improve the comfort of the workers and also increase the safety.

Typical Reusable Insulation Products Are:
  • Acoustic Blankets & Shields
  • Acoustic Blankets For Fan And Blower Housings
  • Hydrophobic Insulation Blankets
  • Safety Fire Blankets
  • Safety Rain Shield Protective Enclosures
  • Safety Spray Shield
  • Safety Throw Blanket
  • Thermal Blankets
Reusable insulation can provide significant energy savings and cost savings in industrial manufacturing facilities. Here are a few advantages:
  • Improved energy efficiency: Blanket insulation helps to keep heat inside the facility during the winter and outside during the summer, which can significantly reduce the amount of energy needed to heat or cool the building.
  • Lower costs: Reusable blanket insulation is a cost-effective solution for insulation because it can be used multiple times. This reduces the cost of insulation over the life of the building.
  • Easy installation: Blanket insulation is simple to install and can be cut to fit any shape or size, making it easy to use in a variety of industrial settings.
  • Durable: Reusable blanket insulation is made of heavy-duty materials that can withstand the wear and tear of an industrial environment.

Jamesbury™ Quadra-Powr™ Spring Diaphragm Quarter Turn Actuators for Use in Both Modulating Control and On-Off Service

Jamesbury™ Quadra-Powr™ Spring Diaphragm Quarter Turn Actuators

Valves provide pressure reduction and flow control through piping systems and are critical to industries that form the backbone of the modern world. The valve actuator is crucial for valve operation. Actuators are powered devices that move valves between open and closed states. The valves can open or close depending on the movement it receives from an actuator; this motion is responsible for controlling the flow and pressure within an industrial system or process.

Jamesbury™ Quadra-Powr™ spring diaphragm QPX series quarter turn actuators are applicable for modulating control and on-off service. These actuators offer an exceptionally long cycle life and are well-suited to operate almost any type of rotary valve. The QPX actuator provides smooth and efficient quarter-turn valve operation and safe and reliable operation even when minimal supply pressure is available.

Exclusively developed for quarter-turn valve service, Quadra-Powr™ X spring-diaphragm actuators provide safe and reliable operation even when minimal supply pressures are available. Yet they can operate at pressures as high as 7 bar (100 psi).

Industrial Actuators, Valves, and Positioners

Industrial Actuators, Valves, and Positioners

Valves regulate fluid flow to provide accurate control and safety in any given process system, and methods of adjusting valve position are always required.


Commonly, valves are operated with handwheels or levers, although some must be regularly opened, closed, or throttled. In certain conditions, it is not always practical to position valves manually; hence actuators are employed instead of hand wheels or levers. 


An actuator is a mechanism that moves or regulates a device, such as a valve. Actuators decrease the requirement for people to operate each valve manually. Valves using actuators can remotely control valve position, particularly crucial in applications where valves open and close or modulate fast and precisely. 


Pneumatic, hydraulic, and electrical actuators are the three fundamental types. 


  1. Pneumatic actuators employ air pressure to generate motion and are probably the most prevalent type of actuator utilized in process systems. 
  2. Actuators powered by a pressurized fluid, such as hydraulic fluid, are called hydraulic actuators. Typically, hydraulic actuators of the same size produce more torque than pneumatic actuators. 
  3. Electric actuators generate motion using electricity. Actuators usually belong to two broad categories: solenoid or motor-driven actuators. 


Actuators position valves in response to controller signals and can be positioned rapidly and precisely to accommodate frequent flow variations. The instrumentation systems that monitor and respond to fluctuations in plant processes include controllers. Controllers receive input from other instrumentation system components, compare that input to a setpoint, and provide a corrective signal to bring the process variable (such as temperature, pressure, level, or flow). 


You have a control valve when actuators pair with flow-limiting or flow-regulating valves. Generally speaking, control valves automatically restrict flow to provide accurate flow to a process to maintain product quality and safety. 


Control valves can be linear, where the stem moves the valve disk up and down like globe valves, or rotational. Rotary control valves include butterfly valves, which open or close with a 90-degree rotation. The pneumatic diaphragm and electric actuators are the most prevalent on linear and rotational control valves.


Some valves require long stem travel or substantial force to change position. A piston actuator's higher torque is preferable to diaphragm actuators in these situations. Examples of piston actuators are rack and pinion and scotch-yoke designs. 


Single-acting piston actuators control the air pressure on one side of a piston, and with higher air pressure, the piston moves within the cylinder and turns the valve. The air on the opposite side of the piston exits the cylinder via an air vent. With decreased air pressure, the spring expands, causing the piston to move in the opposite direction. 


If air pressure falls below a predetermined threshold or is lost, the spring will push the piston to the desired position, referred to as the "fail" position (open or closed). 


A double-acting piston actuator lacks a spring and has air supply ports on both ends of the cylinder. Increasing air pressure to the supply port moves the valve in one direction. Higher pressure air entering from the opposite supply port pushes the valve in the opposite direction. Filling the cylinder with air and releasing air from the cylinder is regulated by a device known as a positioner. 


Typically, the control of pneumatic actuators occurs from air signals from a controller. Some actuators react directly from a controller, for instance, a pneumatic 3-15 PSI controller output. Sometimes, a controller signal alone cannot counteract a valve's friction or the process media's fluid pressure. This situation requires a separate, high pressure air supply and modulating it with a pneumatic or electro-pneumatic positioner. These devices regulate a high pressure air supply to ensure that an actuator has enough torque to position a valve accurately. The positioner responds to a change in the controller's air, voltage, or current signal and proportions the high pressure air to the actuator. Connecting the actuator stem to the positioner is a mechanical linkage. This mechanical connection is also known as a feedback connection. The link moves as the actuator stem moves up, down, or rotationally. The location of the connection informs the positioner when sufficient movement coincides with the controller's air signal. The controller's signal transmits to the positioner instead directly to the actuator, and the positioner regulates the air supply provided to the actuator.


Like other process components, actuators are prone to mechanical issues. Since actuator issues can negatively impact the operation of a process, it is essential to be able to recognize actuator issues when they occur. Frequently, an operator can notice an actuator fault by comparing the valve position indication to the position specified by the controller. For instance, if the position indicator shows the valve closed, but the flow indicator on the controller indicates that flow is still passing through the valve, the valve seat and disc are likely worn, enabling leakage through the valve.


Because there are so many different styles and designs of actuators, positioners, and valves and so many industrial applications, the combination possibility matrix is vast. You must discuss your application with a knowledgeable, experienced valve expert. The success of your project in terms of product quality, system cost, maintenance, and safety depends upon it.

The Armstrong VERIS Verabar®


Veris Verabar Mead O'Brien
The Armstrong Veris Verabar averaging pitot flow sensor provides unsurpassed accuracy and reliability. With its solid one-piece construction and bullet shape, the Verabar makes flow measurement clog-free and precise. Its unique sensor shape reduces drag and flow-induced vibration, and the location of the low-pressure ports eliminates the potential for clogging and improves signal stability.

Veris Verabar Flow

Veris Verabar Mead O'Brien
Verabar - Superior Signal Stability and Greater Resistance to Clogging

Clogging can occur in low-pressure ports in or near the partial vacuum at the rear of the sensor. The Verabar design finds the low-pressure ports on the sides of the sensor, forward of the fluid separation point, and turbulent wake area, virtually eliminating clogging and producing an extremely stable signal.

Verabar - Flow Coefficient
Verabar - Accuracy You Can Trust And the Data to Back It Up

The unique and exclusive breakthrough in improved accuracy derived from developing a verified theoretical model predicts the Verabar flow coefficients. The verified theoretical model eliminates the need for calibration tests to characterize the flow coefficients. Without such a model, the uncertainty of the flow coefficients dramatically increases, and expensive calibration is required. Empirical test data from independent laboratories verified the theoretical model and flow coefficients as a constant, independent of the Reynolds number and within ±0.5% of the predicted value. The Verabar Flow Test Report (ED-100) includes the theoretical model and test data derivation.

Verabar Flow Data


Verabar - Lower Drag and Extended Turndown

Golf balls fly farther because they have a dimpled surface that lowers aerodynamic drag. The grooves and roughness on the Verabar’s frontal surface apply the same principle. This simple design feature relieves the partial vacuum at the rear of the sensor, reducing the pressure drag and extending the accuracy and rangeability to very low velocities.

Inflatable Seat Butterfly Valves - Posi-flate


The Posi-flate Inflatable Seat Butterfly Valve uses air pressure to inflate the seat against the disc and create a bubble-tight seal, resulting in minimal friction as the disc opens and closes. The Posi-flate inflatable seat automatically compensates for wear, providing longer valve life. 


The resilient seated butterfly valve forces the disc into the static seat, causing impingement between the disc and seat, resulting in excessive damage, premature wear, and valve leakage. 


The Posi-flate inflatable seated butterfly valve offers less friction, low torque, less wear, and longer valve life!


Unlike other valves that seal with friction, Posi-flate's unique butterfly valve uses an inflatable seat to seal with air pressure. Thus it requires less torque and a smaller actuator, resulting in lower overall valve cost. Plus, the seat automatically compensates for wear, providing longer valve life.


How Posi-flate Butterfly Valves Work


Closed, unsealed

As the valve rotates into the closed position, the disc makes only casual contact with the seat, reducing friction, wear, and torque requirements.


Closed, sealed

After the valve is closed, the seat inflates against the disc providing more sealing surface and an even pressure distribution against the disc.


Open, unsealed

Before the valve opens, the seat deflates. The disc is then free to rotate to the open position.


Posi-flate inflatable seated butterfly valve applications include:


  • Material Control and Cut-Off Valve Applications
  • Double Dump Valve Assembly Applications
  • Dryer Valve Applications
  • Outlet Valve Applications
  • Pneumatic Conveying Valve Applications
  • Vacuum Valve Applications

Benchmarking Energy Consumption of Equipment and Facilities

Benchmarking Energy Consumption

Note: The following post discusses energy consumption and benchmarking in general. As you'll see, the most significant component of plant energy consumption is typically process heating/steam consumption. Mead O'Brien, along with products and technologies from Armstrong International, Shannon Global Energy Solutions and Everactive, has the people, equipment, and experience to assist you in developing a strategy to significantly improve your plant steam and hot water systems conservation efforts. Contact Mead O'Brien for more information.


While each manufacturing facility and production process is unique, every industry uses similar equipment. Most facilities' major energy consumers concentrate energy use on a few basic systems: lighting, process heating, steam generation, compressed air, pumping, and fans. Making a list of Significant Energy Users (SEUs) can assist in focusing efforts on projects that will result in the most significant savings. 


To create a list of SEUs, group equipment by location, type, or process, and record information such as estimated operating hours, rated power, and loading. The diagram below depicts the various systems and equipment that consume energy in a typical plant and the differences in potential energy savings between facility systems. 


Plant Energy Consumers

The 80/20 rule applies here. Eighty percent of energy consumption is accounted for by 20 percent of the equipment or processes. Only a few energy systems typically consume most of the energy at a site. Consider concentrating your efforts on these systems.

 

Comparing facilities, processes, or equipment over time is the baseline. 
Benchmarking: Comparing the energy performance of facilities, techniques, or equipment over time to similar internal or external facilities. 


Benchmarking the performance of your SEUs is a great place to start on your energy-saving journey. If you work in a multi-facility organization, you can use benchmarking to compare facilities and combine the results to identify best practices. Even if you only have one facility, benchmarking against similar equipment within your facility allows you to identify areas for improvement and best practices of your own. 


Benchmarking can include practices such as understanding, comparing, and optimizing maintenance measures and equipment energy use (such as boiler blowdown or compressed air leaks). 


Benchmarking your energy data allows manufacturers to compare their equipment, process, or facility to others and identify potential energy savings opportunities. Benchmarking understands how you currently operate (for example, how much energy your plant or a single SEU uses) and compares that to similar operations. 


Benchmarking internally (comparing similar steam boilers in the same facility), company-wide (comparing air compressors in different facilities), industry-wide (information from surveys, trade groups, etc.), or all three. Benchmarking can be intimidating for many small manufacturers because, unlike your larger industry peers, you don't have a large pool of plants, manufacturing lines, and heavy equipment for a fair comparison. However, even the smallest manufacturers must compare their major energy users to best practices. 


Energy savings occur in systems such as compressed air, steam generation/distribution, or process heating. Determine the types of energy resources used by each piece of machinery or process. A paint booth, for example, will use compressed air to spray the paint, exhaust fans, and process heating to cure the painted product. This activity will aid in the identification of individual energy-consuming systems and their supporting equipment. 


Small or medium-sized manufacturers may lack a large energy team, a large budget, or the resources to conduct large-scale energy audits or significant equipment overhauls. Turning to outside experts can be extremely helpful provide proven expertise all for reasonable costs.
