Pressure reducing valves made of gunmetal, with ­female threaded connections

This pressure reducing valve is an alternative to the larger versions, in cases where only small flow volumes are required or the medium in question is compressed air. With an outlet pressure of max. 50 bar the pressure reducing valve is used, for example, to control the starter air on ships. It goes without saying, that it holds all the necessary marine approvals of the various bodies such as Germanischer Lloyd etc. This valve is used in many industrial applications particularly for compressed air and neutral gases.

For the protection of:

  • commercial and industrial plants

against too high supply pressure.

Pressure reducers are used, if within a piping system despite of varying pressures on the inlet side a certain pressure must not be exceeded on the outlet side.

  • compressed air supply plants
  • pneumatic control units
  • pressure booster plants air-side
  • shipbuilding industry and offshore plants
