In metallurgical plant, the medium may be very aggressive, abrasive and corrosive, if coal powder is contained in the fluid. Hard and abrasive coal particles will damage the valve sealing face and reduce the service life.
Nowdays, Foyo full-lined ceramic ball valves are installed in these coal containing applications in metallurgical, and other similar industries.
Advanced ceramics, including zirconia ceramics and high purity alumina ceramics, silicone nitride and silicone carbide are used for manufacturing these valves. These advanced materials have excellent physical properties and stable chemical properties. Due to these advantages, Foyo ceramic ball valves give reliable performance in aggressive mediums, and have at least 3 times the service life of metal seated valves. Also, it may have five times the service life of teflon lined valves.
Festo pneumatic actuators and Siemens E/P positioners are assembled with Foyo Full lined ceramic ball valves for precise and stable controlling.
