  • Applications

    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
