Manual Knife Gate Valve

○ Equipped with steel reinforced rubber sealing ring to increase the service life of the sealing ring

○ Equipped with flushing device

○ Two type new bracket, increasing the strength of the bracket

○ Mud, slurry is highly recommended

○ The bidirectional self sealing manual knife gate valve uses two rubber valve seats to clamp and press the gate plate to achieve a sealing effect. When the gate plate is fully opened, the two sealing valve seats automatically match and press against each other, forming a fully rubber short pipeline. Combined with the internal pressure of the pipeline, the strength sealing effect is better. At the same time, when the valve is fully open, the gate plate can be replaced online without the need to remove the entire valve for gate plate replacement and maintenance, which affects the normal operation of the pipeline. The main feature of this valve is a full diameter rubber sealed seat, which has strong wear resistance and full diameter flow resistance. Suitable for use on industrial and mining pipelines that require wear-resistant valves.
