Safety and control devices for burners and appliances burning gaseous fuels – Automatic shut-off valves for inlet pressures up to and including 500 kPa

Scope

This document specifies the safety, design, construction, and performance requirements and testing for
automatic shut-off valves for burners and appliances burning one or more gaseous fuels, hereafter
referred to as “valves”.

This document is applicable to valves with declared maximum inlet pressures up to and including
500 kPa and of nominal connection sizes up to and including DN 250.

Addition:

This document is applicable to:
— electrically actuated valves;
— 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;
— valves where the flow rate is controlled by external electrical signals, either in discrete steps or
proportional to the applied signal;
— valves fitted with closed position indicator switches.

An assessment method for valve designs is given by this document.
