Ceramic Valve

What is a Ceramic valve ?

Ceramic material Ceramic engineering, Engineering courses, Ceramic materialsA ceramic valve is a valve with any ceramic trim, ball, seat, disc or lining. The use of ceramic in the valve is what distinguishes it from other valves. Furthermore because of the disadvantages, engineering challenges and benefits of using ceramic it is not a common valve to select. Ceramic valves will only be used in specific situations.

Why is it called a ceramic valve ?

It is called a ceramic valve because it makes use of and/or contains ceramic elements

what does a ceramic valve do ?

A ceramic valve is using in a pipe system to control the flow of liquid or gas through the pipeline much like any valve. A carbon steel or stainless steel body is commonly designed to protect the ceramic trim from damage by mechanical shock or sudden thermal changes. Advanced ceramic materials are preferred to be used in the manufacturing process; some examples are alumina (an aluminum oxide), zirconia and silicon nitride (very hard and temperature stable material).
The desired characteristics of ceramic valves are more evident when compared to steel or other traditional materials. Using ceramic in valves have the advantage of being resistant to wear while also having lower mass. An especially excellent corrosion resistance, abrasive resistance and wear resistance for ceramic valves means they are often used in applications of high corrosion and abrasion, such as Flue-gas desulfurization, and pneumatic refuse conveying systems - which is a pipe system that uses compressed air or a vacuum to propel solid objects.
