Typical Applications:

Knife gate valves have simple structure and knife gates can cut off medium which contains solid particles and fibers, but for some very hard particles or serious erosive mediums, general metal seated knife gate valves will be washed out easily. As a professional and experienced ceramic valve manufacturer, FOYO also developed ceramic knife gate valves to solve this problem.

FOYO’s ceramic knife gate valves are very suitable for those mediums containing  firbers and hard solid particles, such as below listed typical applications: Mining slag,Coal washing,Ash Slurry,Suspension,Ash,Grain,Quartz Sand,Metallurgical dust,Ores,Granules.

Design Features:

Product type

1. Ceramic knife gate valves have one piece integral body design to reduce  flow resistance

2. Inlet seat and outlet seat are ceramics materials. Because high hardness and high strength of high pure 99% Al2O3 ceramics, Foyo ceramic knife gate valves have much longer service life than general metal seated knife gate valves in similar conditions.

3. The gates of ceramic knife gate valves are hardened with nitriding treatment, Tungsten carbide T.C. or hard Chrome to improve working performance.

4. Several structures of ceramic knife gate valves are available on customers' requirement.

5. The actuation of FOYO ceramic knife gate valves can be hand wheel, pneumatic cylinder, electric motor and hydraulic actuator, special requirements are available on customer’s requirement.
