The Beaver Quarter-Turn Pneumatic Actuator has a rack and pinion mechanism which transforms linear pressure applied on the rack into a rotational turn of the pinion.
The T01 model is a double-acting actuator which operates in both directions, having two ports for air and two pistons. It provides constant torque output and has a fail-last safety function.
The T02 model is a spring-return actuator with one port through which pneumatic force is supplied and a spring mechanism that provides the opposing force. It’s used for fail-open or fail-closed functions.
This compact actuator provides a wide range of rotational outputs for quarter-turn valves. It’s suited for use with dry or lubricated air, with maximum particle size not exceeding 30 microns.
