Sensitive and precise pressure control
Small volume and light weight
Easy regulating and maintenance
Excellent sealing performance
Built-in strainer, to prevent the guide piping system from being blocked
PR300 lightweight pressure reducing valve can automatically reduce high pressure at the inlet to a stable low pressure at 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 is generated, the return fluid will enter the air chamber to close the valve to prevent the fluid from back flow.
