Structural features:

1. The middle cavity of PN≤16Mpa adopts flange connection;

The middle cavity of PN≥20Mpa adopts pressure self-tightening seal;

2. Elastic gate.

3. The valve stem has an upper sealing function.

4. The sealing surface is overlayed with CR13, carbide or body, which is wear-resistant, high-temperature resistant and has long service life.

Flange connected gate valve is suitable for nominal pressure ≤42Mpa

It is used as a medium for cutting off or connecting pipelines on pipelines of various systems such as petroleum, chemical industry, thermal power stations, etc. with an operating temperature of ≤650°C.
