Type G-4


Pilot operated pressure reducing valve

■ 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.


Sizes (Cast Steel):1/2'' to 6'' CL150 & CL300 flanges

The G-4 pressure regulators are fitted with stainless steel valves and seats to use on steam, air and gases up to a maximum temperature of 800°F. Also may be modified for oxygen gas service.
