White Paper "Valve Actuation: The When, How and Why of Actuator Selection"

Valve automation dramatically improves control, precision and efficiency. While these advantages
must be weighed against higher capital and operating costs, actuators are frequently found to be a cost-effective investment for most oil and gas applications. This white paper, courtesy of Flowserve, is excellently written and thorough.

TOPICS DISCUSSED
  • Is automation right for your application?
  • The actuator hierarchy
  • Electric actuation
  • Pneumatic actuation
  • Hydraulic actuation
  • Specialized actuators for pipeline applications
  • Gas-powered actuators
  • Electrohydraulic (EH) actuators
  • Future developments
