Today, there are seven sets 6” 600LB high pressure pneumatic ball valve with limit switch in workshop. These ball valves were arranged in a line as regular. Ball valve is one of main product which COSOVALVE (CSV) provided, especially large size ball valve. But pneumatic actuators were not produced by us. We also purchase them from factory which is specialized in actuator. Hence, we also have great cooperation with ROTORK, AMUA, LIMITORQUE and BIFFI etc.
