Type G-4

G4

Pilot operated pressure reducing valve

Features
■ Extremely compact design.
■ Constant outlet pressure is maintained right up to the maximum rated capacity of the valve, and is unaffected by changes in the flow rate or inlet pressure.
■ Very high flow rates can be achieved due to the full lift capability of the main valve assembly and the design of the valve body.
■ Positive shut off is ensured by accurate guiding of the pilot and main valve assemblies. Non-metallic trims are available to give dead tight shut-off on air and gas applications.
■ Available in Bronze, Cast Iron, Stainless Steel and Steel.
