The ATL Tank Vent Valve allows the fuel tank to maintain a constant and safe status by minimising build up of pressure and allowing the tank to vent should a vacuum be experienced.
This particular vent is a -10 size, which is suitable for an in-line installation. This particular variant contains a pressure relief facility 'blowing off' should the in tank pressure increase to 200mbar, float chamber valve and a gravity activated rollover valve ensuring flow shuts off should the vehicle rollover, meeting FIA requirements.
