Compact actuators offer a versatile rack-and-pinion design for use on 0.5-3" (15-80mm) Eccentric Plug Valves. The compact design allows the actuator to be mounted for a low profile assembly. Compact actuators are available in sizes to meet a wide variety of torque requirements.
The rack-and-pinion design of PowerRac® Actuators provides high-operating torque for accurate control in modulating services, and high opening torque for on/off services. The unique square collet coupling rigidly clamps the drive pinion to the valve shaft, eliminating backlash in the drive connection. This rigid connection allows thrust from the cylinder to precisely position the valve.
Designed specifically for use on quarter-turn valves. The actuators are designed for on-off or modulating service in either a fail-open or fail-closed mode. Action can be easily changed in the field with no additional parts required.
Feature a cast -iron housing with sintered bronze bearings on each end of the input shaft for durability and performance. The ductile iron gear provides strength and a long service life. Available with hand wheel, chain wheel or a 2" square nut, with external position indication and are available with safety lockout devices.
