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 standard: API 600、GB/T 12234
- 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
- Optional pressure seal bonnet type.
- Optional solid-wedge type
- Optional non-rising stem structures
- Optional jacket structure
