VALQUA Medium Flange Gasket (Valflon Jacket Gasket S Type)

VALFLON jacketed gaskets are gaskets that combine corrosion resistance and elasticity, with an outer skin made of fluororesin (PTFE) with excellent corrosion resistance and a core made of joint sheet with excellent elasticity and flexibility. They have excellent chemical resistance. They are coated with PTFE, so they can be used with a wide range of chemicals. They cause very little contamination of the liquid in contact with the liquid, making them suitable for high-purity chemicals. They can be used in a wide range of temperatures, from low to high. Compared to PTFE alone, they have significantly improved creep and stress relaxation properties at high temperatures, providing stable sealing performance. The S type is a gasket that combines non-asbestos sheets above and below the joint sheet to further improve the flow of the PTFE outer skin.
Joints of various chemical equipment such as pipe flanges, towers, tanks, kettles, etc. that handle corrosive fluids. Joints of various chemical equipment such as glass-lined pipe flanges, towers, tanks, kettles, etc. where the gasket seat has large undulations or distortions and the tightening force is restricted. Joints of various chemical equipment such as pipe flanges, valve bonnets, level gauges, towers, tanks, kettles, etc. that handle highly polar solvents that swell or dissolve rubber. Joints of pipe flanges, towers, tanks, kettles, etc. where a decrease in product purity or a change in taste due to the extraction of organic components or elution of metal ions from the gasket is unacceptable.
