Typical Applications:
In many bulk material handling systems, such as coal fired power plant, steel plant, cereals transport system, cement transport systems, etc., generally in these applications, pneumatic conveying method is used to reduce manpower demand, and improve system efficiency and reliability. But abrasion of valves is a big problem that causes customers a lot trouble.
The valve sealing surface and flow path of these valves are destroyed seriously by high speed solid materials. FOYO develops Ceramic Double Disc for these applications which works quite well for coal fired power plants all over the world.
Double Disc Gate Valves are suitable for any bulk materials handling system including the mediums listed as below: Silicon Powder, Alumina Powder, Coal Powder, Cement, Lime Stone Powder, Magnesium Powder, Quartz Sand, Metallurgical dust, Ores, Fly Ash, Granules.

Design Features:
Product type
The Ceramic Gate Valve is ceramics-to-ceramics sealing, also named as parallel double disc valve, or ceramic double disc valve or ceramic double gate valve.
The standard end connection of ceramic double disc valves is flanged type, but if the installation space is limited, wafer type is available.
Three piece bodies of Ceramic Gate Valves are very easy for assemble and reliable for maintenance.
Self-cleaning disc design allows disc to move freely and avoid being scratched by solid particles.
Temperature range
Usually working temperature of pneumatic conveying system is not so high, but under some conditions like economizer valves in coal fired power plant, the working temperature may be up to 450 ℃. Then special design of ceramics and packing material will be considered.
Normal working temperature of Ceramic Double Disc Valves: -29 °C ~ +200 °C
High temperature design of Ceramic Double Disc Valves: -29 °C ~ +450 °C
Ceramic Rotating Double Dsic Valves
Valve tightness
The tightness of valve is very important. FOYO has advanced ceramic processing technology and skilled technicians. All ceramic sealing faces of the Ceramic Double Disc Valves are well ground and polished, which ensure Class V leakage as per FCI 70-2.
Other tightness rates upon request.
FOYO Ceramic Double Disc Valves have much longer service life than the other similar products.
Design standards
Valve body ASME B16.34
Face-to-Face: Manufacturer’s Standard, customized length of Ceramic Double Disc Valves is available.
