The Yoshitake GP-2000EN is a pilot-operated pressure reducing valve designed for steam applications. It features a ductile cast iron body, stainless steel main and pilot valves, and an external sensing method to provide highly stable secondary pressure control. With a large-size diaphragm and a high Cv value, it offers significantly improved flow and control capabilities compared to regular valves.

Features

• Stable Control: Large-size diaphragm and external sensing method control reduced pressure more stably.
• High Flow Capability: Since the Cv value is high, flow capability and control capability are significantly improved, one or two sizes smaller than the regular nominal size can be applied.
• Great Sealability: Spherical main valve offers great sealability and great reduction of valve seat leakage (compliant with ANSI Class IV).
• Low Pressure Management: Pressure management at low pressure (0.02 MPa or less) is available (with GP-2000L).

Sensing Pipe Requirement

*1 External sensing is standard. When installing the pressure reducing valve, be sure to connect the provided sensing pipe and joint. Unless the sensing pipe is connected, the valve will not operate. (Available with internal sensing type in different specifications. Note that Cv value of internal sensing type is lower than that of external sensing type.)

Variations

*2 Available with the GP-2000L, reduced pressure of 0.01 to 0.02 MPa, from 15A to 100A, inlet pressure of 0.1 to 0.5 MPa and maximum pressure reduction of 50:1. Available with external pilot type and ASME flanged versions.
