Our bespoke Valve-Tork™ Pneumatic Actuators feature an innovative and compact rack and pinion design. All the critical components are manufactured using state-of-the-art CNC machines, following ISO quality assurance standards. They can be set to either fail-open or fail-close and come in 15 different sizes, both in double and single acting versions. With torque figures in ranges 9 to 3500 Nm, these actuators are ideally suited to operate quarter-turn valves such as plug, ball and butterfly valves.
