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