Typical Applications:

Same to ceramic double disc valves, ceramic rotating double disc valves have been widely used in many bulk material handling systems, such as coal fired power plant, steel plant, cereals transport system, cement transport systems, and so on. Generally in these applications, pneumatic conveying method is used to reduce manpower demand, and improve system efficiency and reliability. Because there is huge abrasion for this system, sealing surface and flow path of valves are destroyed seriously by high speed solid materials. Foyo develops ceramic rotating double disc valves for these severe applications which work quite well in many coal fired power plants all over the world.
ceramic rotating double disc 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

If your working service is not listed above and you are not sure if Foyo ceramic rotating disc valve is suitable for your systems, please feel free to contact Foyo’s experienced engineer for professional proposals.

Design Features:

Product type

The ceramic rotating disc valve is ceramics-to-ceramics sealing and parallel double discs. However if it’s used as a gravity discharge valve, single disc design is much better than double disc design. By applying double disc valve design for this valve, when valve is shut off, bulk material will drop into tank because of its gravity and will not accumulate in the valve body. Thus ceramic rotating double disc valves will never been blocked.
The standard end connection of ceramic rotating disc valve is flanged type, but if installation space is limited, wafer type body is available. Foyo can provide any end connection per customers’ requirement.
Self-cleaning disc design allows the discs 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 special conditions like economizer valves in coal fired power plant, working temperature may be up to 450 ℃. Then special design of ceramics and packing material will be considered.

Normal working temperature of ceramic rotating double disc valves: -29 °C ~ +200 °C
High temperature design of ceramic rotating double disc valves: -29 °C ~ +450 °C

Valve tightness

The tightness of ceramic rotating disc valve is very important. Foyo has advanced ceramic processing technology and skilled technicians, all ceramic sealing faces of ceramic rotating 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 rotating double disc valves have much longer service life than other similar products.

Design standards

Valve body ASME B16.34
Face-to-Face: Manufacturer’s Standard, customized length of ceramic rotating double disc valves is available.
Valve Testing as per API 598
