Which actuator is best for the control valve?
Hydraulic actuators are good choices for large-size and high-pressure class valves having high force or torque requirements for operation at high speed. Hydraulic actuators are more precise than pneumatic actuators since hydraulic oil is not compressible.
How long do valve actuators last?
To summarize, mechanical equipment such as shutdown valves, control valves, actuators, and accessories such as positioners are designed keeping in mind a plant’s life of around 25 years.
What causes an actuator to break?
Normally, failure is caused by application errors, such as side loading, incorrect wiring, poor mounting fixity, excessive loading, and exceeding duty cycle.
