Pressure Reducing Valve

Pressure reducing valve simply opens by applying spring pressure to a diaphragm. The outlet pressure from it pushes the diaphragm upward at the bottom of the diaphragm, closing the valve. The spring pressure takes over and pushes the valve stem downward, allowing the valve to open when the outlet pressure drops below the valve's set point. The pressure beneath the diaphragm starts to outweigh spring pressure as the outlet pressure rises and approaches the required pressure, driving the valve stem upward and closing the valve. Under specific circumstances, pressure reducing valves can be used to prevent water hammer.
We are Manufacture of Pressure Reducing Valve
