Water pump rubber muffle noise Check Valve
Water pump rubber muffle noise check valve with high quality PVC Clear Sheet is usually used for drainage pipeline in industries & cities, and also for water outlet of high-rise housing/hotels and compressing water pump. PVC Rod has well chemical stability .In full consideration of environmental requirement, this check valve choose the inclined plate structure to save energy.Plastic Sheet has the effect of flame retardant.
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.
