YB43X Proportion type Pressure Reducing Valve
Brief Introduction.
YB43X is Proportion type pressure reducing valve,as its floating piston ends have different cross-sectional area,there will be a fixed pressure differential between the valve inlet and outlet,thereby change the outlet pressure conditions,achieve the purpose of decompression.It is usually applied in high buildings,pump stations and fire-protection systems.
