● valve reduces high upstream pressure and produce a steady lower downstream
pressure, free from the influence of upstream pressure or flow changes. ● valve is either less dynamic pressure can be less static pressure. ● valve downstream pressure can be based on system requirements continuously adjustable within a certain range. ● can quickly close the valve in case of sudden closure of its upstream and downstream pipelines to reduce static pressure. Under normal circumstances, the proceeds valve pressure is not higher than 10% of the corresponding dynamic pressure. ● adjustable Pressure Reducing Valve from the pipeline pressure to start, the pilot valve automatic control, both less dynamic pressure, but also reduced static pressure reducing valve. The valve will reduce the high upstream pressure and produce a steady lower downstream pressure from the upstream pressure and flow changes. The downstream pressure can be obtained by adjusting the bolts on the decompression valve guide to change. When the upstream pressure is down to the desired pressure setting, the pilot valve to the main valve to open to the greatest extent. When downstream pressure exceeds the set pressure value (for example, the static pressure relief valves downstream of pipeline water does not flow in the fire hydrant system case), the valve immediately shut down to reduce the static pressure, so not only can meet the routine decompression of the water supply system to keep the system requirements and more stringent fire hydrostatic, high reliability, to avoid the problem of string pressure systems from the fundamental.
