H71W-40C Cast steel wafer lift check valve produced by Shanghai Biao yi Valve Co., Ltd. is composed of valve body, disc and spring.
It is installed horizontally or vertically in the pipeline system to prevent backflow of medium. The disc closes quickly and the water hammer pressure is small; The flow channel is smooth and the fluid resistance is small; The action is sensitive and the sealing performance is good.
H71W-40C Check valve can be widely used in water supply and drainage, fire-fighting, building, HVAC and industrial systems. Water, gas, oil, acid, lye, hydrogen, ammonia, fire pipeline and other media can be used.
For example, it can be installed at the outlet of the water pump, which can avoid water hammer, water hammer sound and destructive impact, and achieve the purpose of preventing reverse flow and protecting equipment, with good energy saving effect.
Main features
H71W-40C Wafer Lift type cast steel check valve has short stroke of valve disc, light valve disc, spring assisted closing and fast closing speed. The structure is short in length, small in volume, light in weight, small in fluid resistance, reliable in sealing, stable in opening and closing, wear-resistant, long in service life, free from medium influence in oil pressure and slow closing, and has good energy-saving effect, which brings great convenience to the installation, handling, storage of valves and pipeline layout.
