ADJUSTABLE PRESSURE REDUCING& STABILIZING VALVE ENYX741X
A. ADJUSTABLE PRESSURE REDUCING& STABILIZING VALVE PURPOSE
ENYX741X 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.
B. ADJUSTABLE PRESSURE REDUCING& STABILIZING VALVE FEATURE
- 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.
- Easy debugging and operation. Just adjusting the adjustable screw of the pilot valve can get an accurate and stable outlet pressure.
- 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.
