PZ73W manual (wafer) knife type valve body structure with short length, light weight, the valve seat sealing surface against medium erosion, sealing surface, uniform compression joint is tight in the closing process, the valve seat sealing surface of the dust and tar scraped away and the sewage is convenient, prevent dielectric leakage and other advantages. Suitable for use in gas pipelines containing dust or tar.

Structure characteristics:

Knife gate valve is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, knife gate valve can be fully open and fully closed, can not be adjusted and the throttle. When the knife gate valve is closed, the sealing surface can only be sealed by the medium pressure, that is to say, the sealing surface of the ram is pressed to the other side of the valve seat to ensure the sealing of the sealing surface, which is the self sealing. Most of the knife type gate valve is forced seal, that is to say, when the valve is closed, the gate should be pressed to the valve seat by external force, so as to ensure the sealing surface sealing.

Product features

1, ultra short structure length, saving materials, can greatly reduce the overall weight of the pipeline system

2, the effective space is small, can effectively support the strength of the pipeline, can reduce the possibility of vibration of the pipeline

3, the selection of austenitic stainless steel gate, corrosion resistance greatly improved, can effectively prevent the gate corrosion caused by sealing leakage

4. The upper sealing packing adopts flexible PTFE, which is reliable in sealing and easy to operate

5, the gate with the knife, can effectively brake off all kinds of debris in the medium.
