Puretorq Vane Type Actuator

Puretorq, using the vane design, utilizes the rotary-to-rotary motion principle providing the reliability for modulating and simple on/off applications at costs more competitive to Rack & Pinion actuators

Dual ISO5211 mounting pads on top and bottom of actuator allows for easy choice of valve direct mounting Dual integral Namur VDI/ VDE 3845 top works dimensions for limit switches and positioners Composite material:Exceptional mechanical strength and corrosion resistance (also available in aluminum) Easy stop adjustment at each end of stroke for accurate seating Easy stop adjustment at each end of stroke for accurate seating h Direct NAMUR mount pad for solenoid valve Patented static Tri-seal for reliable sealing technology; provides up to millions of cycles Dual female output shafts on the top and bottom of actuator in accordance to ISO5211/DIN3337 for easy direct mounting with the valve

Features

Puretorq Actuators are the Ideal Design for Modulating

High friction piston o-ring seals (wear items) Small air passageSlop or hysteresis Side load compensation "wear pads" (wear items) Valve open adjustment Common leak path, o-ring shaft seal (wear item)

Conventional Rack & Pinion actuators can not avoid the hysteresis caused by the gap between the rack and the pinion, inducing motion errors when utilized in modulation application. Puretorq actuators do not have these issues and can provide the reliability for modulating and simple on/off application.
