ATWs anti-crystallization and wear-resistant ball valves are specially developed for working conditions involving easy-to-crystallize and highly abrasive fluid. Nano-coatings can effectively inhibit the crystallization and adhesion of fluid as well as the scouring by solid particles, significantly extending the service life. These valves meet the stringent requirements in chemical, metallurgical and other fields for high sealing performance, low maintenance costs and stable operation under harsh working conditions.
