What is a Ceramic ball valve

Ceramic ball valve is characterized by heat resistance, corrosion resistance, wear resistance, high hardness, low temperature deformation and high sealing surface precision. The use of ceramic properties as a valve manufacturing material has broad prospects.
In recent years, a variety of ceramic materials have been used in the manufacture of valves. Ceramic ball valve generally use ceramics to make the components, or add a ceramic coating on the metal surface.

Nominal size of ceramic ball valve: DN50 ~ DN300 (2 "~ 12")
Pressure grade: PN10 ~ PN40
ANSI 150 ~ 300LB (lb)
Body material: Carbon steel WCB, A105
Stainless steel 304, 316, 304L, 316L
Ball valve inner material: structural ceramics
Connection: Flange connection
Drive mode: manual,pneumatic, electric actuator
Test pressure: strength test 1.5 times nominal pressure
Seal test 1.1 times nominal pressure
Ash test 1 times the nominal pressure
Ceramic ball valve service temperature: -20 ~ 300℃

Ceramic ball valve application

Ceramic ball valve can be used as flow control valve or shut-off valves for corrosive fluids and high-temperature fluids containing solid materials. Depending on the application, you can choose valves with over-flow components that are all ceramic, or valves that only their important components are sprayed with ceramic. 
    
 

Prospect of ceramic ball valve

Valve manufacturing and research institutions in various countries attach great importance to the research and development of ceramics. In the future, ceramics will become an economic material for valve manufacturing.
However, for users, the brittleness of ceramics is still a defect. Although they understand that ceramics have many advantages, the practical use of ceramic valves is not very reliable.
In the future, we should strive to carry out the strength analysis of ceramic components and establish a damage probability calculation system while remedying the weakness of ceramics. The production of highly reliable ceramic ball valve that reassure users is still an important research topic for valve technicians.
