Double-acting and spring-return, NAMUR interface.

Actuators & Control Valves Series

Pneumatic Actuator (Rack & Pinion / Scotch Yoke)

Rack-and-pinion actuators serve compact quarter-turn valves; scotch-yoke units deliver high breakout torque for large ball and butterfly valves. Double-acting or spring-return fail-safe, NAMUR interface throughout.

As part of the VTXFLOW actuators & control valves range, every pneumatic actuator (rack & pinion / scotch yoke) is produced under our certified quality system — from in-house casting and CNC precision machining to 100% pressure and seat-tightness testing before shipment, with EN 10204 3.1 material certificates supplied.

Double acting & spring return (fail open/close)
Rack & pinion to 8,000 N·m; scotch yoke to 500,000 N·m
NAMUR VDI/VDE 3845 accessory interface
Anodized / epoxy / SS housings
