Pressure reducing valves made of gunmetal, with ­female threaded connections

All characteristics and technical features of the stainless steel versions also apply to the series 684 made of corrosion-resistant gunmetal. The fully relieved valves which therefore even out inlet pressure variations are available with and without secondary venting and each in a diaphragm or a piston version. Pressure adjustment is carried out without tools via the ergonomically formed hand-wheel. The extremely small pressure loss in the pressure adjusting area leads to these high-performance pressure reducing valves having almost no competition.

For the protection of:

  • commercial and industrial plants

against too high supply pressure.

Use of pressure reducing valves, when in a piping system inspite of varying pressures on the inlet side a specific pressure on the outlet side must be kept.

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