V-ball this ball valve are fixed, but also single-seat sealing valve, regulating valve in the best performance, 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. Valve Co., Ltd. Shandong Everbright produce such a wide range of application types of valves, reliable, no internal leakage, leakage phenomenon, frequent switching is not stuck, rusty V-ball manufacturers, the majority of chemical plants, thermal power plants, steel plants, printing and dyeing, food plants the best choice. V-type valve sealing material is mainly based on fluid properties, pressure, temperature and other factors to select. Also, consider the following aspects: ① chemical properties in V-ball vendors, requiring the seal material has a high resistance to corrosion and dissolution properties. ② In terms of physical and mechanical properties, should have a high strength to withstand long-term effect of the fluid pressure, and can repeatedly disassembly; good elasticity and plasticity; sliding friction coefficient and low coefficient of expansion; self-lubricating properties and excellent wear resistance, and having good impermeability and non-hygroscopicity. ③ thermodynamic performance, the request can heat, cold, and abrupt changes in temperature resistant Shandong V-ball, and good thermal conductivity. It also requires extensive source material, processing, easy and low cost. Shandong V-ball | V-type valve | Valve Model Everbright Everbright Limited provided by Shandong valve. Valve Co., Ltd.
