Industrial Valve Sealing Surface Wear and Repair

Over time, industrial valve disc and seat sealing surfaces naturally wear out due to frequent opening, closing, and exposure to the working medium. This wear reduces the sealing performance, which can lead to leaks and affect system operation, potentially causing safety risks. Therefore, repairing the sealing surface is essential to maintain industrial valve performance. The primary method for restoring sealing is grinding. For valves with mild wear, grinding can restore their sealing ability....
