Pressure Reducing Valve

SHIELD manufactures two types of Pressure Reducing Valves, such as Globe Type and Angle Type. SD-PRV-G (globe) and SD-PRV-A (angle) Pressure Reducing Valves automatically reduce a higher inlet pressure to a steady lower outlet pressure regardless o􀁂 changing 􀁜ow rate and􀀎or varying inlet pressure. The valves pilot control system is very sensitive to slight downstream pressure 􀁜fluctuation, and will automatically open or close to maintain the desired pressure setting. The downstream pressure can be set over a wide range by turning the adjustment screw on the CRD pilot control. The adjustment screw is protected by a screw-on cover, which can be sealed to discourage tampering.

Our diaphragm actuated design is proven highly reliable and easy to maintain. We o􀂁er both aglobe or angle pattern with a 􀁂ull range o􀁂 adjustments. These valves are also available in a variety o􀁂 material options. Epoxy coating is strongly recommended or all re system valves (excluding bronze valves). The SDPRV- G and SD-PRV-A can be supplied with optional

internal and external epoxy coating o􀁂 the main valve wetted surfaces.

This Valve is indispensable when the fire pump pressure exceeds 12-bar.
