BS EN 161:2007
Automatic Shut-Off Valves For Gas Burners & Gas Appliances (British Standard)
This European Standard specifies the safety, construction and performance requirements for automatic shut-off valves for gas burners, gas appliances and similar use, hereafter referred to as valves.
This European Standard covers type testing only. It applies to valves with declared maximum inlet pressures up to and including 5 bar, for use on burners or in appliances using fuel gases of the first, second, and third families. It applies 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 this European Standard. It also applies to valves where the flow rate is controlled by external electrical signals, either in discrete steps or proportional to the applied signal. It also applies to valves fitted with closed position indicator switches.
The documentation below is intended for free use in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations.
