GB/T1852-2008 Cast steel steam pressure reducing valve 

Pressure Reducing Valve is an intelligent Valve that uses the energy of the medium itself to regulate and control the pipeline Pressure. For domestic water supply, fire water supply and other industrial water supply systems, the outlet pressure of the main valve can be adjusted through the pressure reducing pilot valve of the regulating valve. The outlet pressure will not change due to the change of inlet pressure and inlet flow. The outlet pressure can be safely and reliably maintained at the set value, and the set value can be adjusted as required to achieve the purpose of pressure reduction. The pressure reducing valve features accurate decompression, stable performance, safety and reliability, convenient installation and adjustment, and long service life. The Big Flow Steam Pressure Reducing Valve mainly controls the fixed outlet pressure of the main valve. The outlet pressure of the main valve will not change due to the change of the inlet pressure or the change of the outlet fl…
