Gas Powered Actuators for the Oil and Gas Industry

Gas Powered Actuators for the Oil and Gas Industry

The gas-powered scotch yoke actuator is a mechanical device designed to convert linear motion into rotary motion, primarily used for valve actuation in the oil and gas industry and other industrial applications requiring precision control of fluid flow. This actuator is particularly advantageous for heavy-duty and high-torque applications, offering reliable and efficient operation with minimal maintenance. Here's a detailed overview of how it operates and its primary application:

Operation:


  1. Gas supply: The gas-powered scotch yoke actuator uses pressurized gas as the driving force, which, depending on the specific application and site requirements, the gas source is a natural gas pipeline, an onsite compressor, or bottled gas.
  2. Pneumatic cylinder: The gas enters the pneumatic cylinder, which is the core component of the actuator. The cylinder contains a piston that moves linearly when pressurized gas is applied.
  3. Scotch yoke mechanism: The linear motion of the piston is converted into rotary motion using the scotch yoke mechanism. The scotch yoke consists of a yoke (a slotted, U-shaped component) attached to the piston rod and a pin mounted on the rotating output shaft. The yoke slides along the pin as the piston moves linearly, causing the output shaft to rotate.
  4. Output shaft: The output shaft's rotation is transferred to the valve stem, causing the valve to open or close, depending on the direction of the rotation. The shaft is connected to the valve using a coupling, which ensures proper alignment and torque transmission.
  5. Spring return mechanism: Some gas-powered scotch yoke actuators have a spring return mechanism, which enables the valve to return to a predetermined fail-safe position in the event of a loss of gas supply or system failure.


Primary application: The primary application of the gas-powered Scotch yoke actuator is in the oil and gas industry, where it controls various types of valves, such as ball valves, butterfly valves, and plug valves. These valves are essential for regulating the flow of oil, gas, or other fluids in pipelines, processing plants, and other facilities.


The actuator's high torque capabilities make it suitable for heavy-duty applications, such as large-diameter or high-pressure valves. Additionally, the gas-powered design offers several advantages over electric or hydraulic actuators, including lower operating costs, reduced environmental impact, and compatibility with remote or hazardous locations where electricity or hydraulic power may not be readily available.

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.

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.

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.

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.
