Rotary Motion Valve Electrohydraulic Valve Actuators and Hydraulic Valve Actuators
from Rotork plc
GO actuators are designed to use pipeline gas as the motive power source. Gas is delivered to oil tanks that convert it into hydraulic pressure without the gas entering the hydraulic cylinder. This pressurised hydraulic oil is used to drive our industry recognised scotch yoke quarter-turn or linear... [See More]

from Rotork plc
GP/GH range scotch yoke actuators are designed to operate ball, butterfly and plug valves requiring a rotary, quarter-turn movement for either on/off or modulating duty and can be supplied with symmetrical or canted torque arms. The robust design has been proven in thousands of diverse applications... [See More]
