    Characteristics

    The sealing surface of stainless steel valves is welded with Stellite or cobalt chromium tungsten alloy, with a hardness of ≥ HRC58, a temperature resistance of up to 600 ℃, and a leakage level of ANSI Class IV. It is suitable for high-temperature and high-pressure corrosive media (such as high-temperature dilute nitric acid).

    Advantages

    1. Wide temperature range stable working ability

    The thermal stability of stainless steel material is better than that of carbon steel. Conventional stainless steel gate valves can operate stably within the range of -200 ℃ (ultra-low temperature liquid nitrogen working condition) to 600 ℃ (high temperature steam working condition), and are not easily oxidized or deformed at high temperatures. There is no risk of brittle fracture at low temperatures. Compared to carbon steel gate valves, it has a wider temperature range and is suitable for more extreme working conditions.

    2. High sealing reliability and low maintenance cost

    Metal hard seal type: The sealing surface is welded with hard alloy (such as Stellite alloy), combined with the wear-resistant characteristics of stainless steel substrate. The sealing surface is not easy to scratch or corrode, and the leakage level can reach ANSI Class IV. The service life is 3-5 times that of carbon steel gate valves.

    Soft seal type: The valve seat is embedded with PTFE/PFA and other fluorine materials, tightly fitting with the stainless steel gate plate, which can achieve ANSI Class VI zero leakage. The stainless steel material is not easy to rust, avoiding valve stem jamming and reducing maintenance frequency.
