  Actuator Requirements for Control Valves

  Posted by Chaitanya E on July 16, 2020 at 1:13 pm

  Spring return pneumatic diaphragm/piston type actuators should be used.

  Where service condition or valve design exclude the use of above mentioned principle, double acting
  pneumatic piston actuators should be applied.

  Hydraulic or electric actuators may be used for special
  applications.

  By loss of signal/supply the valve shall take the position required.

  Electro-pneumatic positioners should be used for remote control.
