V-type valve sealing material is mainly based on fluid properties, pressure, temperature and other factors to select. Also, consider the following aspects: ① in chemical properties, require the seal material with high resistance to corrosion and dissolution properties. ② In terms of physical and mechanical properties, should have high strength V-ball suppliers, can long withstand the pressure of the fluid, and can be repeated assembly and disassembly; good elasticity and plasticity; sliding friction coefficient and low coefficient of expansion; wear resistance and self excellent lubricating properties, and having good impermeability and non-hygroscopicity. ③ thermodynamic performance V-ball manufacturers, the request can heat, cold, and abrupt changes in temperature resistance and good thermal conductivity. It also requires extensive source material, processing, easy and low cost. The main features of V-ball are as follows: (1) switch quickly and easily (2) sealing Currently, the vast majority of valve seat are made in V-ball with Teflon and other flexible materials, metals and metal materials clap Sealing composition, often referred to as a soft seal. In general, the soft seal tightness easily guaranteed, and the sealing surface of the machining accuracy and surface roughness requirements are not very high.
