Diaphragm-controlled, spring-loaded for smaller flow rates
The pressure reducing valve type DM 505 is an automatically regulating proportional regulator for small flow rates. It is used for pressure regulation downstream of the valve and is suitable for liquids, gases and steam. The valves are made entirely of stainless steel and offer excellent corrosion resistance.
The design allows for easy maintenance: the diaphragm or spring module can be replaced without special tools.
