Scotch Yoke Valve Actuators

Description: This standard provides general requirements for the development of specifications for pneumatic scotch yoke actuators. This document applies to actuators with a maximum allowable operating pressure (MAOP) of 250 psig with a compressed gas (i.e., instrument air).

Description: All GF Piping Systems actuators can be used as open/close or control actuators. The double-acting design means that the valve is opened or closed by the actuator applying compressed air. Depending on the requirement, the springs can open or close. The single-acting
