YX741X adjustable pressure reducing& stabilizing valve purpose
YX741X Adjustable Pressure Reducing & Stabilizing Valve is mounted on the pipeline of high buildings and other supply systems to lower the higher upper-stream pressure to the one used for the down-stream in line with the requirements.
YX741X adjustable pressure reducing& stabilizing valve features
a.Reliable pressure reducing effect. Either the inlet pressure or the flow variation will not influence the outlet pressure; both dynamic and static pressures can be reduced.
b.Easy debugging and operation. Just adjusting the adjustable screw of the pilot valve can get an accurate and stable outlet pressure.
c.Good effect of energy saving. The valve body is so designed as full-path streamline straight-flow type, resulting in the small pressure loss, big flow, small volume and light weight.
