Yoshitake GP-1210 is a remote air-loading type pressure reducing valve designed for steam applications. It features a ductile cast iron body with JIS Rc screwed connections and operates with an inlet pressure range of 0.1 to 1.0 MPa. The air-loaded design allows for precise reduced pressure control from 0.05 to 0.9 MPa by adjusting the loading air pressure.

Features

• Significantly improved workability and durability compared with conventional pressure reducing valves.
• Spherical main valve offers great sealability and great reduction of valve seat leakage (compliant with ANSI Class IV).
• Compliant with SHASE-S106 Pressure Reducing Valves (by the Society of Heating, Air-Conditioning and Sanitary Engineers of Japan).
• Simple and robust internal structure.
