1.Introduction of Flange Stainless Steel Gate Valve

Flange stainless steel gate valve is mainly used to cut off or connect media in pipeline. Flange stainless steel gate valve is widely used. Flange stainless steel gate valve should be installed horizontally in pipeline.

The opening and closing parts of the gate valve are the disc, and the movement direction of the gate valve is perpendicular to the fluid direction. The flange stainless steel gate valve can only be fully opened and fully closed! Gate valve is mainly used to connect or cut off the medium in the pipeline, not suitable for regulating the medium flow.

4.Advange of Flange Stainless Steel Gate Valve

The fluid resistance is small. The medium channel inside the gate valve body is straight through, and the medium does not change its flow direction when flowing through the gate valve, so the flow resistance is small.

Flang stainless steel gate valve is easy to open and close. When opening and closing, the movement direction of the ram is perpendicular to the flow direction of the medium. Compared with the stop valve, the gate valve is easier to open and close.

The flow direction of the medium is generally unrestricted. The medium can flow in any direction from both sides of the gate valve to achieve the purpose of connecting or cutting off. It is easy to install and suitable for pipeline where the flow direction of medium may change.
