A certain angle is formed between the two sealing faces of the single-disc or double-discs wedge gate valve and perpendicular to the pipeline axis. It is mainly used for switching on or off the medium within pipelines, that is, it is used in a full open or close manner.

The gate valve is widely applicable for oil industry, chemical industry, and power station.

Design Features

Design standard: API 600、GB/T 12234. GOST DIN EN
Small flow resistance for fluid.
Only a small force is required for opening/closing.
No limitation on the flowing direction of the medium.
During opening and closing process, the friction between the disc wedge and the seat is small, so the sealing is reliable ensuring tightness and long service life.
The valve is designed in a back-seat structure.
The valve stem sealing is realized by the collaboration of flexible and woven graphite. ensuring a more reliable tightness.

Valve Type:Cast Steel Globe Valve.
Valve Size:1/2”-24”.
Pressure Rating:Class 150 – 1500.

Standards:

Check valve is opened or closed by the valve disc to rotate around the spindle outside the valve seat; and it is an automatic valve when it is automatically opened or closed by the force generated by the medium flowing within the pipeline. Its major function is to prevent the backflow of the medium in the pipeline, reverse rotation of the pump and its driving motor, and discharge of the medium in the container.

Design Features
