POWERRAC > Cylinder Actuators >

PowerRac > actuators are designed for all quarter turn valves. They feature a time and application proven rack and pinion system for converting linear motion to rotary. PowerRac > PowerRac > ή actuators are designed and sized to DeZURIKs line of quarter turn valves. By matching valve torque requirements, each actuator is sized to ensure the lowest cost, most economical actuator is used. > Ү actuators feature a high opening torque, neces-sary for on-off applications, and they also maintain high operating torque throughout the full stroke, important on modulating service.A unique externally adjustable...

For applications, where fail-safe operation is a requirement, PowerRac > ή The PowerRac actuator features a rugged rack and pinion design with hardened steel gears. Nominal play in the gears combined with a rigid coupling between the valve shaft and positioner drive allows thrust from the cylinder to precisely position the valve on modulating service. 3 actuators are available with a spring return option. The spring is caged at the factory for increased safety. Double acting actuators can be converted to spring return action by adding a spring cartridge. Unlike other actuators, adding a spring...
