Self-operated valves

Self-operated valves are used for temperature and pressure regulation. They are cost-efficient, since external power sources are not required.

The valves are suitable for many different applications, for example, liquids systems covered by the Pressure Equipment Directive 97/23/EC.

In the operation of self-operated valves, the existing system pressure or temperature is utilised for the generation of the necessary position signal and of the actuator’s driving power. Our product range includes self-operated valves for pressure reduction, pressure containment, and temperature adjustment.
