Application:
Developed in response to FIA regulation, appendix J -258 for Fuel Cell Ventilation Systems, the VR series valve performs the following three functions.
- In normal conditions the valve acts like a regular rollover valve, closing off when the tank inclines more than 90° to prevent fuel escape during an emergency.
- The valve contains a unique hollow aluminum flotation ball to shut off any fuel that surges up the valve chamber.
- When the valve is closed a 200 millibar by-pass prevents pressure build-up within the tanks.
For no compromise sports and race cars.
These valves always remain open to the atmosphere unless under G-Forces generated from hard braking and accelerating, or during an inversion – i.e. the car has rolled over in an accident. The valves are suitable for competition vehicles including F1 and the American series.
