Product Information

Product Overview

  • The rubber flap check valve is mainly composed of three parts: valve body, valve cover, and rubber flap. The rubber flap is made of steel plate, steel rod, and reinforced nylon cloth as the substrate, with rubber coated on the outside. The valve flap switching life can reach 1 million times. The valve adopts a full flow area design, featuring low head loss, not easy to accumulate debris, and easy maintenance. This valve is mainly used in water supply and drainage systems, and can be installed at the water pump outlet to prevent backflow and water hammer damage to the pump. The valve can also be installed on the bypass pipe of the reservoir inlet and outlet pipes to prevent pool water from flowing back into the water supply system.
