Swing Flex Check Valve

The rubber disc in the valve is made of steel plate, steel rod and reinforced nylon cloth, and the outer layer is covered with rubber. The valve disc switch life can reach 1 million times. H44X (SFCV) series rubber disc check valve is designed with full flow area, which has the characteristics of small head loss, easy to accumulate debris, easy maintenance and so on. H44X (SFCV) series rubber disc check valve is mainly suitable for horizontal installation of water supply and drainage system, and can be installed at the water outlet of water pump to prevent backflow and water hammer damage to the pump. The H44X (SFCV) series rubber disc check valve can also be installed on the bypass pipe of the water inlet and outlet pipe of the reservoir to prevent the water from flowing back into the water supply system. Check valve is generally suitable for cleaning medium, and is not suitable for medium with solid particles and high viscosity.
