Description

The R1 PowerRac® Spring-Return Actuator is a quarter-turn enclosed rack and gear cylinder actuator.
The R1 PowerRac® Spring-Return Actuator is used for on-off or modulating control on ½"–3" PEC
Eccentric Valves. The R number designates the 1" radius of the actuator gear. A choice of 4" and 6"
(100 mm and 150 mm) cylinder diameters is offered. The 4" cylinder is offered with one spring size
while the 6" cylinder has two spring sizes.
The actuator is available as a spring-to-open or spring-to-close actuator. The spring action may be
reversed by removing the spring-return cylinder assembly and mounting it on the opposite end of the
gear housing.
A lockable model of the PowerRac® Spring-Return Actuator is also available. See "Lockable Model"
