RTV VALVE QW Series Self-sealing knife gate valve is to use two rubber seats on the clip pressed the knife a sealing effect. When the knife is fully open, the two seat seals combined together tightly, the pipeline pressure will make sealing better, while the valve is closed, the gate can be arbitrarily removed convenient maintenance, no need to remove the entire valve repair and does not affect the normal operation of the pipeline. The main characteristics of the valve bore full rubber seal seat, has a strong anti-wear properties and all-pass run off continuity. Suitable for use on those requirements valve wear mining.
