Circuit valve
What is the purpose of the water fall prevention valve?
- In the open heat storage tank type air conditioning, the water in the cold / hot water return pipe is filled with water when the pump is stopped to prevent noise and vibration caused by water hammer when the pump is started next time.
- By controlling the pressure at the end of the return pipe, the differential pressure before and after the air conditioner on each floor from the lower floors to the upper floors can be kept constant, so proper flow distribution can be achieved. However, the differential pressure cannot be maintained with the water fall prevention valve using the on-off electric valve.
- It is installed in the return pipe of the open circulation type water heater, and when the pump is started, it returns to the water heater, and when it is stopped, the hot water is retained in the pipe to prevent overflow.
