Diaphragm-controlled, spring-loaded for smaller flow rates
The pressure reducing valve type DM 505 is a self-acting proportional regulator for small flow rates. It is used for pressure control 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 permits easy maintenance: the diaphragm or spring module can be replaced without special tools.
With PN 250 the DM 505 is the high-pressure valve of the series – in return the Kvs value stays at a maximum of 1.4 m³/h. If more flow is required, check the DM 652 with a Kvs up to 22 m³/h.
