Z73X self-sealing bidirectional sealing knife gate valve.knife gate valve VF--ZCC-Z152-CU Customized Customize

The self-sealing knife gate valve achieves a sealing effect by using two rubber valve seats to clamp and press against the gate plate. When the gate plate is fully open, the two sealing valve seats will automatically fit and press against each other, forming a fully rubber short pipe. Coupled with the internal pressure of the pipe, a stronger sealing effect is achieved. Meanwhile, when the valve is fully open, the gate plate can be replaced online. There is no need to disassemble the entire valve for gate replacement and maintenance, which would affect the normal operation of the pipeline. The main feature of this valve is the fully rubber-sealed valve seat with a full diameter, which has strong wear resistance and full flow capacity. It is suitable for use on industrial and mining pipelines where valves are required to be wear-resistant.

Product Features:

Rubber sealing rings with steel ribs increase the service life of the sealing rings

With a flushing device

The two-piece new type of bracket has increased the strength of the bracket

Mud and mineral pulp are especially recommended
