Export Warman Slurry Knife Gate Valves and Knife Valve

JQWL Series Warman Slurry Knife Gate Valve

JQWL air actuated warman slurry knife gate valve

JQWL Series Bi-directional Self-sealing Warman Slurry Knife Gate Valve/Medium Pressure

Product Description: JQWL 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, Sleeve on both sides of seat, Full protection of the valve body, Extend valve life
