Automatic shut-off valves for gas burners and gas appliances

active, Most Current
Organization: CEN
Publication Date: 1 October 2022
Status: active
Page Count: 72
ICS Code (Globe valves): 23.060.10
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. 

This European standard specifies general product requirements for the following controls:

- automatic shut-off valves;

- automatic burner control systems;

- flame supervision devices;

- gas/air ratio controls;

- pressure regulators;

- manual taps;

- mechanical thermostats;

- multifunctional controls;

- pressure sensing devices;

- valve proving systems;

- automatic vent valves.

This European standard applies for control functions that are not covered by a specific control standard for burners and appliances burning one or more gaseous fuels or liquid fuels.

This European Standard applies for AC and DC supplied controls (for controls supplied by stand-alone battery system, battery systems for mobile applications or systems which are intended to be connected to DC supply networks controls see Annex I).

This European Standard is applicable to reset functions used for reset from lockout, e.g. due to ignition failure or temperature cut-out in burners and appliances (see Annex M).

This European Standard establishes methodologies for the determination of a Safety Integrity Level (SIL) and the determination of a Performance Level (PL) (see Annex J, Annex K and Annex L).

This European Standard gives guidelines for environmental aspects (see Annex N).

This European Standard does not apply to mechanical controls for use with liquid fuels.

The protection against environmental impact in open air (i.e. capable of withstanding UV radiation, wind, rain, snow, dirt deposits, condensation, ice and hoar frost (see IEV 441-11-05:2005), earthquake and external fire) is not covered by this standard.

This European Standard should be used in conjunction with the specific control standard (see Bibliography).

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.
