Fail-Safe, Multi-Voltage Motorised Valves with Spring Return
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.
