Rubber Disc Swing Check Valve

The Rubber Disc Swing Check Valve is also called a check valve or a check valves. Its function is to prevent backflow of the medium in the pipeline, prevent the pump and its drive motor from reversing, and discharge the medium in the container. The rubber flap check valve is mainly suitable for horizontal installation of the water supply and drainage system, and can be installed at the water outlet of the pump to prevent backflow and water hammer damage to the pump. It can also be installed on the bypass pipe of the water inlet and outlet pipes to prevent the water from flowing back into the water supply system. Check valves are generally suitable for cleaning media and should not be used for media containing solid particles and high viscosity.

The rubber disc swing check valve is mainly composed of three main parts, the valve body, the valve cover and therubber valve. The rubber flap is made of steel plate, steel bar and reinforced nylon cloth, and the outer layer ismade of rubber, and the valve switch life can reach 1 million times. The valve is designed with full flow area, whichhas the characteristics of small head loss, no accumulation of debris and gradual maintenance and so on.The valveis mainly applied to the water supply and drainage system, which can be installed at the outlet of the pump toprevent the reverse flow and water hammer from damage to the pump. The valve can also be installed on thebypass pipe of the water intake pipe to prevent water from flowing back.

Rubber disc swing check valve is used mainly for water supply and drainage system and can be set on the pumpoutlet to prevent the pump from getting harmed by the medium backflow. lt can also be set on the mouth of awater outlet pipe to prevent the medium from backflow. It has simple structure,reliable performance,longdurable,open-close times can be up to over million ones, can suitable for sewage.

1,The rubber disc check valve has a complete 100% flow area, low head loss and resistance to clogging. To ensure long-term reliability, because the valve's reinforced rubber floppy disk is the only moving part, its integral O-ring provides a drop-proof seal under low and high working pressures.
2,The rubber flap check valve has a unique and simple design with only one moving part. The flap does not swing from the hinge pin; it just flexes open. The seat is at a 45° angle. The baffle moves 35° from opening to closing, usually before column reversal occurs. It has non-slam characteristics.
3,The valve does not require regular maintenance. At the same time, the combination of 45-degree seat angle, short stroke and the inherent memory of its flexible disc can provide quick closing and anti-impact operation.
4,Due to the inclined design of the sealing ring of the rubber flap check valve, the closing time is short and the water hammer pressure can be reduced.
5,The valve flap is made of nitrile rubber and steel plate after being pressed at high temperature. It is resistant to erosion and has good sealing performance.
6,It is mainly applied to oil, chemical, food, medicine, textiles, paper making, water supply and drainage, smelting and energy department ,also used as single direction valves.
