Fluid temperature: High temperature fluids (above 450 ℃) should choose high-temperature resistant valves, such as chromium molybdenum steel high-temperature gate valves used in steam pipelines. Low temperature fluids (below -40 ℃) require valves with good low-temperature toughness, and low-temperature ball valves are commonly used in liquid nitrogen and liquid oxygen pipelines.
