Wafer lift check valves are widely used in water supply and drainage, fire protection, construction, HVAC, and industrial systems. Water, gas, oil, acid, alkali, hydrogen, ammonia, special fire pipes and other media can be used. For example: it can be installed at the outlet of a water pump to avoid water hammer, water hammering sound and destructive impact, to prevent backflow and protect equipment, and has a better energy-saving effect.
