An ASTM A182 F904L Gate Valve is a type of valve crafted from 904L grade stainless steel, following the forging material specification outlined in ASTM A182 F904L. These gate valves are specifically designed for applications involving high-temperature service. Gate valves are engineered to either permit media to flow through unobstructed or to completely stop fluid flow. Their primary advantage lies in their straight-through, unobstructed passageway, which minimizes pressure loss.
