- Referenced StandardApproved to ‘R’ regulations (2009 edition). Calibration certificate issued by lNAIL. In certain cases, INAIL regulations (R regulations, 2009 Edition) governing systems with boilers with heat output exceeding 35kW, require the use of a fuel shut-off valve in place of a thermal drain valve. They define a ‘fuel shut-off valve’ as: ‘a positive-action valve, which automatically shuts off the flow of fuel if the water overheats, so that it does not exceed the established safety temperature’. The fuel shut-off valve is a self-operated positive-safety device (operating without the use of external energy).
