What is BS EN 12351 - Industrial valves about?
BS EN 12351 discusses the 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 12351 specifies protective caps for flanged valves with and without internal coating.
The use of protective caps according to BS EN 12351 is limited to protection during transport and storage to prevent the entry of dirt and the damage of the connecting surfaces.
Note 1: The protective caps do not protect against the consequences of improper handling.
Note 2: BS EN 12351 does not apply to protective caps for valves and pipe fittings with welded and threaded ends.
Who is BS EN 12351 - Industrial valves for?
BS EN 12351 on industrial valves is useful for:
- Valves manufacturers
- Valve cap manufacturers
- Design engineers
- Quality control personnel
- Research and development facilities
Why should you use BS EN 12351 - 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 12351 discusses caps for valves with flanged connections that completely cover the port and the sealing surface of the flange and prevent damage.
The design of caps as described in BS EN 12351 is such that when fitted to flanges, they remain attached during normal handling, transport, and storage until they are removed before installation of the valve. The protective caps fit so tightly that no foreign matter and coarse dirt can penetrate which would impede the correct function of the protected part.
BS EN 12351 directs that the protective caps are designed in such a way that the installation of the valve without removal of the protective cap is impossible. It is recommended that bright signal colours be used, preferably yellow or red. If a particular colour is required, it is indicated in the order. The material of the cap is compatible with the material of the valve and shall not cause contamination or corrosion of the valve. Along with these specifications, marking and other requirements for protective caps for flanged valves are also discussed in BS EN 12351. Using BS EN 12351 you can specify protective caps for flanged valves with and without internal coating.
