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 V-type ball valve manufacturer in terms of physical and mechanical properties, should have high strength, able to withstand long-term effect of the fluid pressure, and can be repeated assembly and disassembly; good elasticity and plasticity; sliding friction coefficient and low coefficient of expansion; wear resistance and self V-ball excellent lubricating properties, and has good impermeability and no moisture absorption. ③ thermodynamic performance, the request can heat, cold, and abrupt changes in temperature resistance and good thermal conductivity. Also V-ball manufacturer, also requires extensive source material, easy processing and low cost. V-ball this ball valve are fixed, but also single-seat sealing valve, regulating valve in the best performance of V-ball offer, is equal percentage flow characteristic, adjustable ratio of 100: 1. It has a shearing action between the V-notch and metal seat, especially for fiber-containing tiny solid particles, slurry and other media. It has the same ball rotated 90 degrees operation, except that the cock body is a sphere, a circular through-hole or channel through its axis.
