During industrial operation, control valves are prone to faults such as inaccurate regulation, leakage and jamming, which can be efficiently solved with reference to OUWEI's after-sales service experience. For decreased regulation accuracy, OUWEI's cemented carbide valve cores or wear-resistant ceramic models can be selected, combined with intelligent positioner calibration. For valve leakage problems, OUWEI original sealing pairs and special packing can be replaced, and metal or PTFE seals can be selected according to working conditions. Jamming faults can be resolved by using OUWEI's valve bodies with insulation jackets, rust-proof valve stems and special lubricants. For vibration and noise, OUWEI's anti-cavitation cage-type valve cores are recommended, which decompose high pressure differences and suppress turbulence. In addition, the modular design of OUWEI control valves facilitates maintenance, and the full-life-cycle data-driven operation and maintenance service can early warn potential faults, with a 3-hour rapid response in core production areas.
