Appliction:
Metal seated ball valve is suitable for Cryogenic, high temperature, high pressure, abrasive and corrosive working conditions. It is the ideal equipment to cut off some special medium, such as the solid and gas mixed medium, solid and liquid mixed medium, high-viscosity medium, high-fiber medium, high temperature steam, etc. It is widely used in the coal chemical, petrochemical, papermaking, poly-silicon industries and power stations.
Advantage:
• Ball valve is the valve with the smallest fluid resistance .
• Stem is able to rotated90˚to realize full open or closed, and it is easy to be operated rapidly.
• Utilizing medium pressure to seal, have good sealing performance.
• Stem blow-out proof: sealing force for the valve stem increases with the medium pressure
• Easy to realize automatic control and remotecontrol.
• Smooth passage can efficiently prevent the sedimentand carry out pigging method.
