Yoshitake | Pressure Reducing Valve

Achieves stable pressure control with excellent flow capacity

The GP-2000 pressure reducing valve is a self-operated valve with excellent flow capacity, featuring a large diaphragm that responds sensitively to small changes in secondary pressure, ensuring stable low-pressure control. The GP-1000 series, refined over time, is the culmination of high performance, quality, and durability in pilot-operated pressure reducing valves.


【Main Features】
■GP-2000

・Large-size diaphragm and external sensing method control reduced pressure more stably.
・High Cv value significantly improves flow capacity and control ability. It can be replaced with products one or two sizes smaller than the regular nominal size.
・Hemispherical main valve design offers great seal ability and significantly reducing valve seat leakage.
・Capable of pressure management at low pressures below 0.02 MPa.

■GP-1000
・Compliant with SHASE-S106 pressure reducing valves (by the society of heating, Air Conditioning and Sanitary Engineers of Japan).
・Spherical main valve offers great seal ability and great reduction of valve seat leakage (compliant with ANSI Class IV).
・Operability and durability have been significantly improved compared to conventional pressure reducing valves.
