Vacuum isolation gate valve,gate valve

Product Overview The connection forms of vacuum isolation gate valves are divided into flange and welding, and the driving methods are manual and electric. The vacuum isolation gate valve is suitable for pipelines with working temperatures ≤425℃ and ≤550℃, and the working medium is water, steam or air, serving as an opening and closing device. It is especially suitable for the condensing and vacuum negative pressure systems of steam turbines in thermal power plants, playing a role in vacuum isolation and sealing.

Ii. Characteristics of Vacuum Isolation Gate Valve:

A vacuum-sealed structure packing chamber was designed to isolate the system from the atmosphere, featuring excellent environmental protection performance.

2. The materials are carefully selected, meeting relevant national and international standards, and the overall quality of the materials is high.

3. The sealing pair is advanced and reasonable in matching, which improves the sealing performance and extends the service life.

4. The opening and closing parts adopt parallel gate plates with bidirectional elastic sealing, featuring low friction, easy opening and closing, convenient maintenance, reliable sealing and excellent performance.

5. The valve stem has undergone quenching and tempering as well as surface nitriding treatment, which endows it with excellent corrosion resistance, scratch resistance and wear resistance.

6. The flange gasket of the vacuum isolation gate valve is made of composite materials, which have a large expansion coefficient, good air tightness and ensure reliable isolation of the system from the atmosphere
