Precision-Engineered Alumina Ceramic Valve Core Washers For High-Temperature And High-Performance Applications

Precision-Engineered Alumina Ceramic Valve Core Washers For High-Temperature And High-Performance Applications

Product Overview

Alumina ceramic valve core washers are high-performance sealing components precision-engineered from high-purity alumina (Al₂O₃ content ≥95%). Specifically designed for demanding valve systems in harsh operating conditions, these washers feature exceptional hardness (Hv≥1500) and outstanding wear resistance, significantly extending valve service life while ensuring reliable sealing performance. Widely used in petroleum, power generation, semiconductor, and other high-demand industrial applications.

Primary Applications

Petrochemical Industry: High-temperature valves in refining units, inlet/outlet valves for hydrogenation reactors
Power Systems: Boiler feedwater control valves, steam regulating valves
Semiconductor Manufacturing: High-purity gas delivery system valves
Water Treatment: High-pressure reverse osmosis control valves
Medical Equipment: Sterile fluid control systems
