Y42X/F-16 spring film typePressure reducing valveThe way

This series of pressure reducing valve belongs to the direct acting diaphragm spring reducing valve, water pressure reducing valve. It mainly consists of adjusting spring, diaphragm, piston, seat, valve and other parts. The diaphragm is used to direct the downstream pressure drive valve clack, and the valve opening is controlled to complete the decompression and voltage stabilizing function.

Y42X spring diaphragm pressure reducing valve can replace conventional partition water pipe and save equipment in the hot and cold water supply system of urban building and high-rise building. It can also reduce pressure and stabilize the pressure in the usual hot and cold water pipe network.
 

The film spring type pressure reducing valve has stable voltage regulation and steady operation, and is suitable for the pipeline of water and non corrosive liquid medium.
