The core value of valves lies in precise adaptation to working conditions. OUWEI ball valves deeply cultivate three core fields of petrochemical engineering, pharmaceutical and HVAC, and create exclusive solutions through structural customization and functional optimization, becoming the preferred brand for fluid control in various industries. 【Petrochemical Engineering Field】: OUWEI hard-sealed floating ball valves adopt WCB valve body + hard alloy surfacing sealing surface, resistant to 350℃ high temperature and 100MPa high pressure, with excellent anti-scouring performance in residual oil transmission; explosion-proof and anti-static models are equipped with graphite fireproof sealing rings and spring anti-static devices, maintaining sealing at 650℃ high temperature, with the resistance between the ball and the valve body ＜10Ω, escorting natural gas long-distance transmission pipelines and catalytic cracking units. After a polyethylene plant selected OUWEI fully welded ball valves, the leakage rate was reduced from 0.5% to 0.01%. 【Pharmaceutical Industry】: OUWEI sanitary soft-sealed ball valves are integrally formed with 316L stainless steel, with an inner surface roughness of Ra≤0.8μm, no dead angle for medium retention, and can pass SIP online steam sterilization, meeting the dual certification of FDA and GMP. The microbial contamination rate in pure water systems is 92% lower than that of traditional valves; lined fluoroplastic ball valves are resistant to acid and alkali cleaning media, extending the service life of equipment. 【HVAC Field】: OUWEI threaded soft-sealed ball valves are compact in volume and easy to install, suitable for fan coil units and branch pipes of water separators and collectors, with a 90° rotary opening and closing response speed 5 times faster than gate valves; regulating ball valves are equipped with electric actuators to achieve precise proportional control of flow, saving more than 25% energy in conjunction with building automation systems, and the bidirectional sealing characteristic prevents medium backflow and improves the operational stability of the system.
