Rubber flap check valve

The parts design of the H44X (SFCV) rubber flap check valve mainly consists of three main parts: valve body, valve cover and rubber flap. The rubber flap in the valve is made of steel plates and steel rods and has a service life of up to 1 million times. H44X (SFCV) rubber flap check valve adopts full flow area design, which has the characteristics of small water head loss, not easy to accumulate debris, and easy maintenance. The H44X (SFCV) rubber flap check valve produced by our company is mainly suitable for horizontally installed water supply and drainage systems. It can be installed at the water pump outlet to prevent backflow and water hammer damage to the pump. This 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.

There are many types of valves used in engineering, among which gate valve, globe valve (throttle valve, needle valve), check valve, plug valve, ball valve, butterfly valve and diaphragm valve are the most widely used in chemical equipment.

Check valve: Also known as one-way valve, it is used to prevent reverse flow of fluid. Therefore, when installing the check valve, you should pay attention to the fact that the flow direction of the medium should be consistent with the direction of the arrow on the check valve.
