    \n

    A manually operated isolation valve shall be fitted upstream of the first control device in the gas circuit. Manual isolation valves shall be so designed or positioned as to prevent inadvertent operation but shall be easily accessible and capable of rapid operation when required.<\/p>\n

    If technically applicable, only manual isolating valves complying with EN 331 shall be fitted. For valves outside the scope of EN 331, the safety requirements detailed in EN 331 shall be met at an equivalent level.1)<\/sup><\/p>\n

    They shall be so designed that the “OPEN” and “CLOSED” positions are readily distinguishable (e.g. a 90\u00b0 turn valve if applicable and available).<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
