نوع المنتج
The Ceramic Double Disc 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 Double Disc 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.
Detailed information about working temperature of our Ceramic Double Disc Valves, please contact us at sales@fuvalve.com.
Normal working temperature of Ceramic Double Disc Valves: -29 °C ~ +200 درجة مئوية
High temperature design of Ceramic Double Disc Gate Valves: -29 °C ~ +450 درجة مئوية
Valve tightness
The tightness of valve is very important. FUVALVE has advanced ceramic processing technology and skilled technicians. All ceramic sealing faces of the Ceramic Double Disc Gate Valves are well ground and polished, which ensure Class V leakage as per FCI 70-2.
Other tightness rates upon request.
FUVALVE Ceramic Double Disc Gate 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.

تطبيقات نموذجية:
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. FUVALVE develops Ceramic Double Disc Valves for these applications which works quite well for coal fired power plants all over the world.
Ceramic Double Disc Valves are suitable for any bulk materials handling system including the mediums listed as below: Silicon Powder,مسحوق الألومينا,Coal Powder,Cement,Lime Stone Powder,Magnesium Powder,رمل الكوارتز,الغبار المعدني,خامات,الرماد المتطاير,حبيبات.
