Diaphragm-controlled proportional controller for steam, gases and liquids
The pressure reducing valve type 5801 is a single-seated valve that is balanced on the upstream and downstream side and operates as a proportional regulator without auxiliary energy. It is used for the precise pressure reduction of steam, non-flammable, neutral gases and liquids in energy and process networks.
Thanks to the integrated water reservoir, the diaphragm is protected against overheating at temperatures above 100 °C.
