Product Description

Application and characteristics

The rubber flap in the valve is made of steel plate, steel rod and reinforced nylon cloth as the substrate, and the outer layer is covered with rubber. The valve flap switch life can reach 1 million times. H44X(SFCV) series rubber flap check valve adopts full flow area design, with small head loss, not easy to accumulate debris, easy maintenance and other characteristics. H44X(SFCV) series rubber flap check valve is mainly suitable for horizontal installation of water supply and drainage system, can be installed in the water pump outlet, to prevent backflow and water hammer damage to the pump. The H44X(SFCV) series rubber flap check valve can also be installed on the by-pass pipe of the reservoir inlet and outlet pipe to prevent the pool water from flowing back into the water supply system. Check valves are generally suitable for clean media, and should not be used for media containing solid particles and large viscosity.
