The GP-2000F series of Pressure Reducing Valves from Yoshitake are a Pilot Operated Diaphragm style of reducing valve for Steam applications with ANSI 150 flanges. This valve has superior capacity and performance when compared to the other pressure reducing valves in the range, with inlet pressures from 1 bar to 20 bar acceptable and a maximum reduction ratio of 20:1. A spherical main valve offers great sealability and reduction of valve seat leakage (compliant with ANSI Class IV). Accurate and stable control is achieved with a large size diaphragm and external sensing method. Durability is achieved with stainless steel internals for main valve assembly and the pilot valve assembly.
