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
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.
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.
Packing
Standard export wooden case packaging
Application Scenarios
The stainless steel gate sluice valves, with their core advantages of corrosion resistance and adaptability to clean media, are widely used in industrial and residential pipeline systems for corrosive media, clean fluids, and extreme temperature ranges.
