Overview
List of Accessories
Typical Applications

PR500 pressure reducing valve can automatically reduce high pressure at the inlet to a stable low pressure at the outlet regardless of changes in fluid velocity or inlet pressure, maintain outlet pressure within the preset range by a precise pressure regulator. When outlet pressure exceeds the set range of the pressure reducing valve, the basic valve body and the pressure regulator will automatically close to form a tight seal.

If the optional check feature is selected, when the back pressure generated, the return fluid will enter the air chamber to close the valve to prevent the fluid from back flow.

Typical Applications

If variable and large flow range demands, use multiple PR500 pressure reducing valves in parallel. In case of large flow demand, use two pressure reducing valves simultaneously. In case of small flow demand, the large-sized valve will automatically close, while the small-sized valve will continue to provide the required flow. When setting the pressure regulating range for the valves, the set pressure of the small-sized valve should be about 0.3 kgf/cm² higher than that of the large-sized valve.If the pressure reduction range is large, use multiple PR500 pressure reducing valves in series for sectional pressure reduction.
