MULTI-FUNCTIONAL WATER PUMP CONTROL VALVE ENJD745X
A. MULTI-FUNCTIONAL WATER PUMP CONTROL VALVE PURPOSE
It is mounted on the water pump's outlet pipeline of the high buildings and other water supply systems to prevent of the medium's back-flow and the water hammer and water shock.

B. MULTI-FUNCTIONAL WATER PUMP CONTROL VALVE FEATURES
  1. Good effect of water hammer removal. Integrating the technical principles of water hammer removal by means of slow open, quick close and slow close, so as to prevent of the water hammers at both pump start and stop.
  2. Easy operation. The valve will open or close automatically as per the operation procedures of the pump, once operates the On-Off button of the pump's motor.
  3. Good effect of energy saving. The valve body is designed as full-path straight-flow type, resulting in small pressure loss, big flow, small volume and light weight.
