The Camtorc series actuators are designed to ensure compact and safe operation of valves and dampers with a constant torque being generated throughout the entire pressure stroke of the actuator.

The lack of internal gearing means that backlash is eliminated, making the Camtorc actuator an excellent choice for modulating control applications whilst the unique dual piston design offers excellent characteristics for valves with relatively low Maximum Allowable Stem Torque (MAST) values.

Pros & Limitations

High actuation efficiency in a compact design

Highly efficient and simple, backlash free operation providing extended life of seals and components

Camtorc actuators only utilise steel and stainless steel materials

Significantly reduces the potential for Valve MAST issues occurring

Standard paint finish is an offshore 2-pack epoxy

Torque output is the same as that of the double acting variant of the actuator

All springs are stress relieved after forming to ensure a long life

Exceptionally low wearing providing low maintenance and the optimum Whole Life Cost Solution

High maintenance systems
