Product Description


Water pump rubber muffle noise check valve

Water pump rubber muffle noise check valve is usually used for drainage pipeline in industries & cities, and also for water outlet of high-rise housing/hotels and compressing water pump. In full consideration of environmental requirement, this check valve choose the inclined plate structure to save energy.


Advantages:

1. Good sealing funtion; Opt NBR sealing to reach the good effects of shock absorption,wear resisting,long working life,convenient maintenance;

2. Good to eliminate water hammer. The slow closing way makes the partial backward flow into the system structure, which greatly bring the backward flow impact pressure down when closing the pump, and enimilate the water hammer peak.

3. Silent valve; The inclined palte structure make the check valve operate with no vibration, no noise, to endure the quiet housing environment and save energy.
