FRP flap valve has the function of opening the flow channel in one direction and closing in the reverse direction.
LANDYOUNG FRP flap valve is designed with international standardized standards, customized products such as vinyl ester saturated resin and other raw materials.It is with the top-mounted structure, the connecting bolts of the valve body are reduced under the conditions of high pressure and large diameter, which enhances the reliability of the valve and can overcome the influence of the weight of the system on the normal operation of the valve.
FRP flap valve are widely used in coal chemical, petrochemical, rubber, paper, pharmaceutical, and other pipelines as a media splitting, confluence or flow switching device.
Advantages and features
FRP flap valve has the function of opening the flow channel in one direction and closing in the reverse direction. The valve cover of the flapper uses its own counterweight to automatically open or close the door leaf under the action of the water flow. There is no jamming. The switch should be free and flexible. When the flapper is partially immersed in water, the internal pressure of the pipeline is relatively high. , When the reverse pressure is small, the flapping door allows partial leakage. When the pipeline water pressure increases, the flapping door will automatically close and seal, with a large opening angle and small impact force. The glass steel slap door has strong corrosion resistance, which improves the various defects of the metal slap door that is easy to corrode, difficult to open and close, and easy to be stolen. It is light in weight, high in strength, and durable, making it the best material choice.
