The double-chamber multi-function pump control valve is installed at the outlet of the pump to prevent and eliminate pipeline surges caused by the starting and stopping of the pump.
When the water pump is opened, the inlet pressure gradually enters the valve cavity, so that the valve opens slowly, and the opening speed can be adjusted by the needle valve. When the pump suddenly loses power or stops, The main disc closes quickly under the combined action of its own gravity and the water hammer. The secondary disc closes slowly to prevent the damage of the high-pressure water hammer at the rear end to the front pump; It can be fully opened with less pressure loss.
