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.
