Gate Valve Characteristics

Flange connection cast steel gate valve is suitable for nominal pressure PN1.6 ~ 42.0MPa (Class150 ~ 2500), working temperature ≤ 600 ℃, petroleum, chemical, thermal power station, and other working conditions of the pipeline, cut off or connect the pipeline medium. Its main structural features are:

The China gate valve product structure is reasonable, has reliable sealing, excellent performance, beautiful shape.

Co-based hard alloy is overlaid on the sealing surface, with good wear resistance, corrosion resistance, and anti-scuffing performance, and long service life.

The actuated gate valve stem is tempered and surface nitride treated, with good corrosion resistance and anti-scuffing.

The nominal pressure≥15.0MPa(Class900)The cavity adopts a self-tightening sealing structure, the sealing performance is enhanced with the increase of pressure to ensure the sealing performance.

The valve is equipped with an inverted sealing structure for reliable sealing.

The material of parts and the gate valve types and sizes of flange and butt welding end can be reasonably matched according to the actual working condition or user requirements to meet various engineering needs.
