Piston valve 684 series

diaphragmpressure-reducingfor air

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
