Series 75 Electric Actuator
Specifically designed for rotary valve applications, on/off and modulating.

A time tested, high quality state-of-the-art electric actuator for remote control of quarter-turn valves and other rotary devices. Simple, compact and reliable.

 
Series 75 Electric Actuators from Worcester Controls add a new dimension of operational dependability and flexibility to modern processes controlled by computers, programmable controllers and other electric control equipment. A multi-function capability permits use of the Series 75 actuator throughout the process for on/off, throttling, variable cycle and any analog or digital control. One of the most reliable electric actuators on the market, the Series 75 is lightweight, compact and powerful. 
Its split phase capacitor AC reversing motor or DC motor drives a valve through a sealed, permanently lubricated gear train which offers virtually lifetime maintenance-free dependable operation.

The Series 75 is available in eight sizes and produces torques to 3000 in. lbs'. Housings are designed to TYPE 1 General Purpose, TYPE 4 Watertight, and TYPE 7, Class 1, Division 1 and 2, Group C, D and TYPE 9, Class II, Division 1 and 2, Group E, F, G. A combined location TYPE 4, 4X, 7, 9 enclosure is also available as a "Z" option. A baked polyester finish is the standard coating, but special coatings are available for extreme 'hazardous environment applications. 

Series 75 actuators may be used on Worcester Controls complete line of ball valves, other quarter-turn valves or devices requiring rotary operators. Moreover, their ability to provide power in both directions through selected arcs from 200 through 3000 makes them ideal for control of heating, ventilating and air conditioning duct systems and automatic, remotely operated equipment.
