Electric Ceramic Ball Valve _ Pneumatic Ceramic Ball Valve

Comprehensive information compilation of electric ceramic ball valves and pneumatic ceramic ball valves, combined with mainstream market products and technical parameters:

1、 Product Overview
Electric/pneumatic ceramic ball valves use alumina or silicon carbide ceramics as sealing pairs, driven by electric actuators or pneumatic devices, to achieve reliable cutting or adjustment of high wear and strong corrosive media. Its core advantages lie in:
Wear resistance: The ceramic hardness reaches HRC90, and the service life is 5-10 times that of ordinary metal valves.
Corrosion resistance: It can withstand acidic and alkaline media with pH 1-14, and some models support hydrofluoric acid environment.
Zero leakage: The hard seal design meets the GB/T 13927 Level VI standard.
