What is BS EN 1984 - Industrial valves about?
BS EN 1984 discusses industrial valves. Industrial valves are mechanical devices that open, close, or partially obstruct passageways to regulate the flow of liquid or gas within a system. BS EN 1984 specifies the requirements for steel gate valves that are wrought, cast, or fabricated with end connections flanged, butt welding, socket welding or threaded. BS EN 1984 is applicable to steel gate valves mainly used for industrial and general-purpose applications. However, they can be used for other applications provided the requirements of the relevant performance standards are met.
The ranges of nominal sizes covered is:
- DN 8; DN 10; DN 12; DN 15; DN 20; DN 25; DN 32; DN 40; DN 50; DN 65; DN 80; DN 100; DN 125; DN 150; DN 200; DN 250; DN 300; DN 350; DN 400; DN 450; DN 500; DN 600; DN 700; DN 750; DN 800; DN 900; DN 1000.
Who is BS EN 1984 - Industrial valves for?
BS EN 1984 on industrial valves is useful for:
- Valve manufacturers
- Design engineer
- Quality control personnel
- Research and development facilities
Why should you use BS EN 1984 - Industrial valves?
Industrial valves manage direction or control the flow of a fluid or gas by opening and closing various passageways. Valves play a vital role in most industries involving pipelines or other applications. BS EN 1984 discusses a steel gate valve which is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus, it is used either in fully closed or fully open positions.
Socket welding end valves and threaded end valves as mentioned in BS EN 1984 are limited to the range DN 8 to DN 65. The range of pressure designations for butt welding end valves, for socket welding end valves and threaded end valves and for flanged valves is also described in BS EN 1984. Using BS EN 1984 you can specify the requirements for steel gate valves used for industrial and general-purpose applications.
