The CERAVALVE K-Performance Line valve is a ceramic-lined ball valve for on/off and control applications for highly abrasive and corrosive media, preferably for suspensions. The valves are supplied with a hand lever or gear box as well as with a pneumatic, electric or hydraulic actuator. The actuator is adapted with bracket and coupling. All commercially available actuators can be used as quarterturn actuators. Special connections are possible.
