Rotary Actuators
Type BR31a – Pneumatic Rack & Pinion Rotary Actuator
Size: SRP/DAP 60 – 1200
Rotation: 90oF
Max Torque: 15,000 lbf-in or (1700Nm)
Temperature: -40oF to 176oF (-40oC to 80oC)
The Pfeiffer BR31a pneumatic rack and pinion actuator is designed for chemical and petrochemical applications. This actuator is a rotary motion device ideal for all types of rotary valves. The torque output of the actuator depends on the actuator area, pneumatic supply pressure, spring stiffness, distance traveled, initial compression of the spring, the number of springs internal to the actuator, etc.
