Pneumatic Ceramic ball valves for coal containing material in metallurgical plant

Pneumatic Ceramic ball valves for coal containing material in metallurgical plant

In  metallurgical plant, the medium may be very agreesive, 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.


In the past, metal seated or teflon lined valves are used in these coal containing conditions, but the situation was not satisfactory due to servere erosion and frequent maintenance.

But this bad situation is getting better since Foyo full lined ceramic ball valves are installed in these coal containing applications in metallurgical, further other similar industries.

Advanced ceramics, including Zirconia ceramics and high purity Alumina ceramics, Silicone Nitride and Silicone Carbide. These advanced materials have excellent physical properties and stable chemical properties. Thanks to these advantages, Foyo ceramic ball valves outstanding performance in agreesive mediums, and have at least 3 times service life than metal seated valves and may be >5 times service life than teflon lined valves.


Festo pneumatic actuators and Siemens E/P positoners are assembled with Foyo Full lined Ceramic ball valves for precise and stable controling.
