Rubber flap check valve
Rubber disc check valve adopts full flow area design, with small head loss, not easy backlog, easy maintenance and so on. Valves can last up to 1 million times. The utility model adopts the full flow area design, and has the characteristics of small head loss, difficult accumulation of sundries and easy maintenance. The valve is mainly used for water supply and drainage system, can be installed in the outlet to prevent backflow and water hammer damage to the pump.
Rubber disc check valves are mainly suitable for horizontal installation in water supply and drainage systems. They can be installed at the outlet of the water pump to prevent backflow and water hammer damage to the pump. They can also be installed on the bypass pipe of the outlet pipe of the reservoir to prevent water from flowing back into the water supply system.
The rubber disc in the valve is made of steel plate, steel rod, and reinforced nylon cloth as a substrate, and the outer layer is covered with rubber. The valve disc has a switching life of up to 100 times. The HH (SFCV) series rubber disc check valve adopts a full flow area design, which has the characteristics of small head loss, less accumulation of debris, and easy maintenance.
