The pneumatic soft-seal gate valve employs rubber vulcanization technology to apply rubber lining both internally and externally as a single piece. This ensures the vulcanized valve maintains precise geometric dimensions, with the rubber securely bonded to the gate valve body. It resists detachment and exhibits excellent elastic memory. Compared to traditional gate valves, the Z645X resilient-seated gate valve features a flat bottom design identical to water pipes, minimizing debris accumulation and ensuring unobstructed fluid flow. Conventional gate valves often accumulate debris such as stones, wood chips, cement, paper scraps, and other foreign matter in the bottom groove after water flushing, leading to leakage due to incomplete closure. This issue does not occur with soft-seal gate valves.
