Y416X type direct acting spring film pressure reducing valveDetailed product description：

Structure characteristics and uses of Y416X direct acting spring film pressure reducing valve:
This series of pressure reducing valves belongs to direct acting thin film spring pressure reducing valves. It mainly consists of regulating springs, diaphragms, pistons, valve seats, valve discs and other parts. By using a diaphragm to directly sense downstream pressure and drive the valve disc, the opening of the valve disc is controlled to achieve the function of pressure reduction and stabilization.

The Y416X direct acting spring film pressure reducing valve can replace conventional partitioned water pipes and save equipment in the cold and hot water supply systems of urban and high-rise buildings. It can also play a role in reducing pressure and stabilizing pressure in typical hot and cold water pipe networks.
The Y416X direct acting spring film pressure reducing valve has smooth pressure regulation and stabilization actions, and is suitable for pipelines containing water and non corrosive liquid media.
