HC84X rubber flap check valve is mainly composed of three main parts: valve body, valve cover and rubber flap. The rubber flap is made of steel plate, steel rod and reinforced nylon cloth as backing. The outer layer is made of rubber flap switching life of up to 1 million times. The valve adopts the full flow area type design, has the head loss first small, not easy to accumulate debris maintenance and other characteristics. The valve is mainly used in water supply and drainage systems can be installed in the pump outlet to prevent backflow and water hammer damage to the pump. The valve can also be installed in the reservoir inlet and outlet pipe bypass pipe to prevent backflow of pool water to the water supply system. Rubber flap check valve valve flap is fully lined with nitrile rubber and the valve body beveled metal combination of sealing, flap closing stroke is short, sealing performance is good, can significantly reduce the impact pressure of water hammer.
Product Features
Rubber flap check valve opening and closing parts rely on the flow of media and the power to open or close by itself to prevent the backflow of media valve parts, designed mainly by the valve body, valve cover and rubber flap three main parts. Mainly for horizontal installation of water supply and drainage systems, can be installed in the pump outlet to prevent backflow and water hammer damage to the pump. Can also be installed in the reservoir inlet and outlet pipe on the bypass pipe to prevent backflow of pool water to the water supply system. Check valve is generally applicable to clean media, should not be used for solid particles and viscosity of the media.
