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、High strength

The support and opening and closing parts of the ceramic gate valve are made of metal, and the sealing pair is a precision-machined structural ceramic. The flat contact sealing form is used to make a straight stroke movement, with large shearing force and high strength.

2、Easy to maintain
The ceramic gate valve adopts a three-stage structure, which is easy to install and disassemble. The internal cavity of the valve is designed with a purge function to prevent blockage.

3、Good sealing

The sealing of the ceramic gate valve adopts a spring-compensated self-sealing structure, which can maintain the sealing performance for a long time.

4、High cost performance
The ceramic gate valve has better performance than ordinary gate valves under dry powder conveying conditions without corrosion and cleanliness requirements, and its price is close to that of ordinary gate valves, with high cost performance.

Application areas:

Power plant	Ash removal system, feeding, fly ash transportation
Concentrator	Mineral powder material transportation
Cement plant	Powder conveying
Others	Other powder, dry powder conveying conditions without corrosion and cleanliness requirements

Applicable medium: slurry, pulverized coal, medium containing particulate matter.
