The ball valve are recommed in pipeline to cut off, distribute and change the flow direction of the medium. It needs to be operated with a rotation of 90 degrees and a small rotation moment to close tightly. Ball valves are best used as switches and shut off valves.
Ball valve has many types such as floating ball valve, Trunniou mounted ball valve, V-port ball valve, three-way ball valve, stainless steel ball valve,cast steel ball valve, forged steel ball valve, top entry ball valve, fully welded ball valve and so on.
Different type ball valve meets different work condition. Cast steel ball valves are recommended in pipeline systems with di-reaction, strict sealing performance, quick opening and closing, low noise, cavitation and gasification, minor leakage to the atmosphere, small operating torque and small fluid resistance.
Cast steel ball Valve (Metal Seat ball Valve)are also suitable in petroleum, petrochemical, chemical, electric power, urban construction, the pipeline system with working temperature above 200 degrees.
