What is BS EN 161 - Automatic shut-off valves for gas burners about?
BS EN 161 is a technical specification that specifies the safety, construction, and performance requirements for automatic shutoffvalves for use with gas burners, gas appliances and similar use, hereafter referred to as ‘valves’. BS EN 161 is applicable to valves with declared maximum inlet pressures up to and including 500 kPa (5 bar) of nominal connection sizes up to and including DN 250 for use with one or more fuel gases in accordance with EN 437. BS EN 161 is applicable to electrically operated valves and to valves actuated by fluids where the control valves for these fluids are actuated electrically, but not to any external electrical devices for switching the control signal or actuating energy. An assessment method for valve designs is given by BS EN 161.
BS EN 161 is also applicable to valves where the flow rate is controlled by external electrical signals, either in discrete steps or proportional to the applied signal. BS EN 161 is also applicable to valves fitted with closed position indicator switches. BS EN 161 establishes methodologies for the determination of a Performance Level (PL) in accordance with EN 13611:2007+A2:2011, Annexes K and L.
Note: Provisions for final product inspection and testing by the manufacturer are not specified.
Who is BS EN 161 - Automatic shut-off valves for gas burners for?
BS EN 161 on automatic shut-off valves for gas burners is useful for:
- The petroleum industry
- The fuel and gas industry
- The automation industry
- Pneumatic applications
- All industrial manufacturers
Why should you use BS EN 161 - Automatic shut-off valves for gas burners?
When the level of shaking at a site exceeds the level allowed by the valve, automatic gas shutdown valves switch off the gas to that building. Automatic gas shutoff valves can assist avoid fires caused by gas leakage during earthquakes.
Shut-off valves are used to block compressed air in an industrial automation process and isolate sub-systems when they are not in use. They are designed to safely control compressed air in pneumatic applications. BS EN 161 addresses the marking, installation and operating instructions. BS EN 161 guides you with test methods for the determination of performance level, reliability, and credibility.
