In industries where valves applied, the use of metal valves has become as common as the convention. In applications that metal valves are not functioning well, industry insiders are more used to expect that the improvement of metal materials can resolve the issues. 

However, with the continuous development of industrial facilities and the upgrading of standards and requirements, metal materials are not always the best choice due to their natural properties, causing them unable to operate under severe working conditions. 

Therefore, the development and application of ceramic valves will naturally become an alternative to fill the traditional valve's disadvantages - this is what Johncera strives to do. With advanced ceramics' natural properties and Johncera's mature technology, Johncera's ceramic valves can achieve the below benefits:

 

Corrosion resistance

Johncera's advanced ceramics have very stable chemical properties for most acid-base media, performing excellent corrosion resistance.

 

High strength

Johncera adopts high-performance advanced ceramics as valve ball and lining materials-flange connection, three-stage structure design, forged steel shell, ensuring easy maintenance and high strength.

 

High hardness

Johncera's zirconia ceramics valve balls have hardness up to HRA88, second only to diamond.

 

Wear resistance

Advanced ceramics' ultra-high hardness allows Johncera's ceramic valves to operate against the erosion of solid particles in fluid flow. Also, the conveying medium will not be contaminated by the peeling material caused by scouring.

 

Zero leakage

Johncera's ceramic ball valves adopt a surface contact sealing structure between ball bodies and valve seats. The sealing surface is well polished with high roundness and accuracy. ANSI VI sealing level achieved.

 

Self-lubrication

With precise ground surface between ball bodies and valve seats, Johncera's ceramic ball valves are self-lubricated in the On/Off process with slight resistance and smooth On/Off switch.  

 

Low torque value

Since Johncera's ceramic ball valves are self-lubricated, therefore they have low torque value and easy to switch.

 

Long service life

Because of the abovementioned properties, Johncera's ceramic ball valves significantly extend service life and reduce maintenance rates.
