Interchangeable = Reliable
Intermixable and interchangeable of same size balls/seats, high reliability;
Special alloy coating on sealing surface with no "biting" even under 550°C condition;
Anti-deformation seat design to prevent valve jamming;
Zero leakage under 60-minutes pressure testing after fully degreasing and decontamination!
ATW's alloy coating proposal has completely overcome the technical problem of metal to metal "biting" in high-pressure, high-temperature, ultra-pure gas fluid and degreased applications. It features smooth opening and closing without jamming, fire-proof and anti-static design, and meets or exceeds the request of FCI/702 Class VI leakage standard under long time running.
