An ASTM A182 F22 gate valve is a heavy-duty, forged linear-motion isolation valve engineered with a 2.25% chromium, 1% molybdenum alloy steel body to provide exceptional creep rupture strength and structural stability in high-temperature utility systems. The forged F22 metallurgy delivers a dense, highly uniform grain structure that resists thermal fatigue and oxidation at continuous operating temperatures up to 593°C (1100°F). Featuring a bolted or pressure-seal bonnet and an OS&Y rising stem, the valve drives a robust wedge perpendicular to the flow to achieve a dependable metal-to-metal shutoff. Conforming to design codes like API 602 and ASME B16.34, ASTM A182 F22 gate valves are critically specified for high-pressure steam headers, power plant boiler piping, and refinery catalytic cracking units. Power piping contractors and sourcing networks can maximize high-temperature creep resistance by importing certified ASTM A182 F22 gate valves directly from premier manufacturers in China through our advanced B2B digital marketplace.
