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.
