Main Features

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.

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.

2、Self-cleaning

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.
