PRV Diaphragm Type Hydraulic Pressure Reducing Valve Pilot Valve with Microfilter
The valve is used for domestic water supply, fire water supply and other industrial water supply systems. The outlet pressure of the
main valve can be adjusted by adjusting the pressure reducing pilot valve.
The outlet pressure does not change with the change of inlet pressure and inlet flow. The outlet pressure can be maintained at the
set value safely and reliably, and the set value can be adjusted according to the need to achieve the purpose of decompression.
The valve has the advantages of accurate pressure reduction, stable performance, safety and reliability, convenient installation
and adjustment, and long service life.
