Rotork GP/GH scotch-yoke pneumatic and hydraulic actuator for pipeline valves

Rotork GP/GH is a heavy-duty range of quarter-turn scotch-yoke actuators for pipeline ball valves and butterfly valves, including harsh climatic and corrosive conditions. GP is pneumatic, GH is hydraulic.

On/off and modulating duty, double-acting and spring-return versions. Hydraulics are rated for pressures up to 360 bar (5,220 psi). Several types of manual overrides, including hydraulic ones. Versions for ESD, HIPPS and safety loops, ISO 5211 valve mounting. Torque depends on size, pressure and lever arm.
