An overflow valve provides constant primary pressure for steam, gases and liquids in all energy and process networks, independently of secondary pressure.

Pressure reducing valves reduce the pressure of steam, non-combustible, neutral gases and liquids in all energy and process networks.

Both the pressure reducing valves and the relief valves are pre- and low-pressure side relieved single-seat valves that work as a proportional controller without auxiliary energy. Both consist of the housing with the trim, bellows unit, spring, handwheel and the drive and a water reservoir to protect the membrane against overheating in the case of steam and liquids above 100 ° C.
