Detailed introduction
Overview and Application
Pressure self-sealing cast steel gate valve is suitable for cutting or cutting off pipelines in various working conditions such as petroleum, chemical industry, hydraulic power, thermal power stations, etc., with an operating temperature of 900Lb ~ 2500Lb ≤ 540℃ (of which the P(57)170V working temperature is 570℃). Switch on medium
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.
