Product Description
The 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 the backing, and the outer layer is made of slope-covered rubber. The valve body's opening and closing life can reach 1 million times. This valve adopts a full-flow area design, which has the characteristics of small water head loss, easy accumulation of debris, and easy maintenance. This valve is mainly suitable for water supply and drainage systems, and can be installed at the water pump outlet to prevent backflow and water hammer from damaging the pump. In case of damage, the valve can also be installed on the bypass pipe of the water inlet and outlet pipe of the reservoir to prevent the pool water from flowing back into the water supply system.
