The Hytork® Air Fail Safe Actuator is for larger valves with higher torque requirements, requiring reliable fail safe operation utilising a unique in-built air reservoir giving fail safe action without the torque losses inherent of spring designs.

The Hytork Excel (XL) Series are aluminum rack and pinion actuators meeting ISO, NAMUR, VDI/VDE standards. These heavy duty actuators are available in both double acting and spring return and feature corrosion protection both internally and externally.

The Hytork XL Commando actuator range solves aggressive corrosion problems, where stainless won’t. Uses a proprietary heat treatment and Fluor polymer impregnated body and coated steel pinion.

Hytork® XLW Actuators are specifically prepared for operating by water.
