Fail-Safe, Multi-Voltage Motorised Valves with Spring Return
The FEL Valves range is a Rotary actuator with emergency control function (Fail-Safe) for 2-way and 3-way ball valves that are specifically designed for use with diesel, fuel, or Biofuels.
This is a great product with its 100% automatic shut off, which is widely used in generator fuel systems/diesel systems and similar systems.
Our diesel fail-safe actuator is integrated across many sectors –
- Defence
- Healthcare
- Security
- Energy
- Environment and Agriculture
- Construction
Predominantly used across many applications such as –
- Fuel systems as a fail-safe shut off or opening for a generator set in the event of fire/mains failure.
- Diesel transfer sets in conjunction with pumps as it allows to control the pump due to its status switches
- Automated control (Open/Close) between bulk tanks and day tanks to allow isolation of fuel line.

Safety Notes
- Caution: Power supply Voltage!
- Only authorised specialists may carry out installation.
- All applicable legal or institutional installation regulations must be compiled during installation.
- The device may only be opened at the manufacturer’s site.
- It does not contain any parts that can be replaced or repaired by the user.
- Cables must not be removed from the device.
- The device contains electrical end electronic components and is not allowed to be disposed of as household refuse. All locally valid regulations and requirements must be observed.
- The two switches integrated in the actuator are to be operated either on power supply voltage or at safety extra-low voltage. The combination power supply voltage/safety extra-low voltage is not permitted.
Installation of the Spring Return Motorised Valve
The fail-safe actuator with a ball valve suitable for diesel can be installed upright to horizontal.
*Important Information*
The ball valve may not be installed in a hanging position i.e., with the stem pointing downwards.
