Product overview

Flanged cast steel gate valve. It is widely used in petrochemical industry, power plant and other fields. The applicable medium is oil, water and steam pipeline for connection or cut-off.

Product features

The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.

The sealing surface is overlaid with cemented carbide. Wear resistance, hunger resistance, hazel damage resistance, long service life.

The valve rod has good corrosion resistance and scratch resistance after quenching and tempering and surface silkworm treatment.

The valve is provided with an inverted sealing structure, which is reliable in sealing.

The part material, flange and surfacing end size can be reasonably selected according to the actual working conditions or user's requirements to meet various engineering needs.
