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