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.
