Developed in response to FIA regulation Appendix J-258 for Fuel Cell Ventilation Systems, the VR series valve performs all three functions:
-Under normal conditions, the valve acts as a normal anti-tip valve, closing when the tank is tilted more than 90° to prevent fuel leakage in an emergency.
-The valve contains a unique hollow aluminium float ball to shut off any fuel that rises up through the valve chamber.
When the valve is closed, a 200 millibar by-pass prevents pressure build-up inside the tank.
These valves remain open to atmosphere at all times, unless subjected to G-forces generated by hard braking and acceleration, or during a reversal, i.e. if the car has overturned in an accident.
The valves are suitable for all types of racing cars, including F1.
Connections: 9/16 UNF (JIC6)
