3" Pressure Sustaining and Relief Valve, 3-Way Pilot (7-78 PSI), Flanged
$304.52
Pressure sustaining valve installed in-line, sustains minimum back pressure controlled by a 3-way pilot. The spring loaded membrane of the pilot is sensitive to upstream pressure and opens the valve when the inlet pressure exceeds pilot set pressure. If upstream pressure is below the desired set pressure, the valve will be in closed position. The valve is factory set at 3 bar, which is 45 PSI.
Our pressure sustaining valves feature a patent-pending curved bridge design and allows for a lower opening pressure, higher flow rate, minimal pressure loss, no vibration, and rapid response.

Principle of Operation
When the upstream pressure is lower than the set pressure, valve closes.
When the upstream pressure is equal or greater than desired set pressure, valve begins to open.
When the upstream pressure drops below set pressure, valve closes by pressurizing the control chamber above the diaphragm.
