Skip to Navigation Skip to Search Compact Actuators Compact Actuators A broad range of hydraulic actuators with a choice of rack and pinion, scotch yoke and linear designs suitable for heavy-duty service in the harshest environmental and operating conditions. They provide economical on-off and modulating control for small to medium quarter-turn valves or the option of high break-out torques for quarter-turn valves up to the largest sizes, including models for very high pressure applications. Each configuration is available in double-acting and spring return formats, to provide failsafe operation. Quick-acting scotch yoke and linear designs are also available for critical applications.
