FREE-VALVE wafer double flap fluorine lined check valve is a kind of automatic valve that relies on the flow of the medium itself, and automatically opens and closes the valve double flap to prevent the reverse flow of the medium. The valve adopts the double disc type, the butterfly plate is two semi-circle, and the spring is used to force the return. Due to the lining of corrosion-resistant material, the valve has good corrosion resistance and reliable sealing performance, and is suitable for all kinds of industrial pipeline systems with strong corrosive media.
1.Compact design of the dual flap check valve allows easy installation and service in tight spaces.
2.Easy to install,the valve can be used for horizontal and vertical installation.
3.The valve disc adopts dual type, which can be quickly closed under the elastic force of the spring.
4.A high torsion spring ensures the valve closes as quickly as possible,Springs provide perfect tightness even at low differential pressure.Low water hammer pressure.
5.The lining material is optional, which can be applied to a variety of media ,the valve has good corrosion resistance.
FREE-VALVE wafer double flap fluorine lined check valve is known as dual plate check valves are mechanical valves that permit gases and liquids to flow in only one direction ,preventing process flow from reversing.The valve has excellent anti-corrosive performance and is suitable for a variety of strong corrosion conditions, and is widely used in petroleum, chemical, dyeing, pesticide, acid and alkali making industries, etc.
