Main Features
  • Corrosion


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


    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


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


    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


    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


    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.

Product Details

1、Face Seal 

The valve adopts plane double face sealing structure between sliding disc and seats, and its installation is unrestricted by flow direction. 


During the opening and closing process for the valve, shearing movement will be generated between sliding disc and seats, then it will take media into pipe-line, ensuring body cavity is without accumulated materials.


3、High Strength 

The open and close for the valve are finished by linear motion with small friction coefficient. The valve is suitable used for high temperature & pressure working conditions. 

4、Zero Leakage 

The back of the seats are equipped with automatic compensation system, which has the selfgrinding property and realize zero leakage. 

Application areas:    

Power plant

Desulfurization unit, Lime & lime slurry, gypsum, filtrate, etc.

Chemical plant
