BS 5352 Gate Valves are industrial valves that conform to the BS 5352 standard, which specifies the requirements for steel wedge gate valves 50 mm and smaller. These valves control the flow of fluids within pipelines by using a sliding gate mechanism and are commonly used in the petroleum, petrochemical, and allied industries. The standard ensures the design, materials, testing, and performance criteria are met, guaranteeing reliable operation in various fluid control applications.
