A proven range of pneumatic actuators offering the options of rack and pinion, scotch yoke and linear designs. Rack and pinion actuators provide the most economical on-off and modulating control for small to medium quarter-turn valves. The efficient scotch yoke design creates high break-out torques making them suitable for quarter-turn valves up to the largest sizes. All three configurations have been designed to provide maximum torque output with minimum supply pressure and are available in double-acting and spring return formats. Scotch yoke and linear designs are also available in quick-acting variants.
Double acting and spring return pneumatic quarter turn actuators for on-off and modulating control of valves in heavy duty service. Available for output torques to 750,000 Nm.
Double acting and spring return pneumatic linear valve actuators for on-off and regulating service.
