A complete set of valves and actuators specially designed for opening and closing vacuum pipelines. Our company has many varieties of vacuum valves (including vacuum globe valves, vacuum gate valves, vacuum regulating valves, etc.), which are widely used. They are suitable for working temperatures ≤425℃ and ≤550℃. They can be used under semi-vacuum, intermediate and advanced vacuum conditions. As an opening and closing device, it is especially suitable for steam turbine condensation and vacuum negative pressure systems in thermal power plants. Pressure range: PN16~PN100/150LB~600LB size range: DN15 ~ DN400 Connection type: butt welding, flange Temperature range: -30 ° C ~425°C Leakage detection level: zero leakage Application media: vacuum negative pressure systems in water conservancy, municipal, power plant, petrochemical, metallurgical and mining, liquefied natural gas, food, medicine and other fields

Structural Features
● The movement friction of the sealing surface is small, the opening and closing is easy, and the wear of the sealing surface has an automatic compensation function.
● Simple and compact structure, convenient maintenance and long service life.
● The valve cover packing chamber is equipped with a vacuum sealing structure, which has a self-expanding pressing effect, and the sealing is sealed with a high-strength expansion material, which completely isolates the system from the atmosphere and has good system airtightness.
