BS 341-1 is an international standard that is a part of the BS 341 series that specifies requirements for the design, materials, manufacture, and testing of new and refurbished valves together with the testing, periodic inspection, and maintenance of valves in service, for use with refillable aluminium and steel containers manufactured for the suitable conveyance and storage of permanent, liquefiable and dissolved gases for industrial applications, but excluding valves with outlets conforming to BS 1319.
BS 341-1 applies to valves limited to a charging pressure of 300 bar1 (developed pressures for particular gases may exceed this pressure). BS 341-1 also gives requirements for the design, manufacture, testing, and installation of pressure relief devices, to protect containers up to 130 L capacity from excessive pressure, particularly when exposed to heat.
Note 1: It is essential that pressure relief devices should not be used with toxic gases.
Note 2: BS 341-1 does not include requirements for the selection of valve outlets and materials for gas mixtures, valves for medical applications complying with BS 1319, and ultra-high-purity gases.
Note 3: BS 341-1 does not cover valves for liquefied petroleum gas (LPG).
BS 341-1 on industrial valves specifications is useful for:
Industrial valves are mechanical devices that govern the flow of liquid or gas inside a system by opening, closing, or partially obstructing channels. The most significant benefit of utilizing this type of valve is the decreased production and maintenance costs.
BS 341-1 provides its users with the general classifications, material requirements, inspection, testing, and maintenance of valves. Using BS 341-1 guidelines ensures high quality, reliability, and durability for better efficiency and quality management at the manufacturing level.
