Y42X type membrane pressure reducing valve product introduction
Membrane
pressure reducing valve is mainly composed of regulating spring,
diaphragm, piston, valve seat and valve flap. Direct sensing of the use
of the diaphragm downstream pressure-driven valve disc, valve opening to
complete decompression regulator function. This product in the city
building, high-rise building hot and cold water supply system, can
replace the conventional district water pipes, saving equipment. Also in
the usual hot and cold water pipe network, played the role of
decompression regulator. This product pressure regulator, steady voltage
stability, suitable for water and non-corrosive liquid medium pipeline.
