Ball valves are widely used in the pipeline to cut off, distribute and change the flow direction of the medium. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. Ball valves are best used as switches and
shutoff valves.
Ball valve has many type such as floating ball valve, trunnion 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,sulfur resistance ball valve.
Cast steel ball valves (soft seat) are recommended in pipeline systems with bi-reaction, strict sealing performance, constriction channels, 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) are suitable for petroleum, petrochemical, chemical, electric power, urban construction, the pipeline system with working temperature above 200 degrees.
