FIRE VALVE – FEL TFV THERMOSTATIC, CAPILLARY 1/2″ The FEL Valve’s ‘TFV’ was the first capillary-operated fire valve to incorporate an integral shut-off facility as part of the reset mechanism.
All TFV fire valves are suitable for use with Class C and D fuels as well as LPG, and provide automatic shut-off in the event of an overheat within a fuel-burning appliance and fail-safe shut-off in the event of capillary or sensor failure.

TFV Temperature Ranges: 66°C to 72°C and 86°C to 95°C, the upper-temperature limits of 72C and 95C are used to indicate the individual ranges. TFV Flow Rates: The TFV range of valves have high flow rate characteristics, making them ideal for suction lift applications, 1/2′ valves are rated at 360 liters/hr, measured at a 1.2m head. TFV Applications: All TFVs are suitable for use with suction or gravity head fuel systems at pressures of –0.8 bar vacuum and 3 bar positive head.
