Product overview

H44X(SFCV) the rubber flap check valve is mainly composed of three main parts: valve body, valve cover and rubber valve. The rubber flap is made of steel plate, steel rod and reinforced nylon cloth, and the outer layer is covered with rubber. The service life of the valve flap can reach 1 million times. The valve adopts full flow area design, which has the characteristics of small head loss, not easy to accumulate sundries, simple maintenance and so on. The valve is mainly applicable to the water supply and drainage system and can be installed at the water outlet of the pump to prevent backflow and water hammer damage to the pump. The valve can also be installed on the bypass pipe of the inlet and outlet pipe of the reservoir to prevent the pool water from flowing back into the water system.
