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 contains 8mm push on ends, which is suitable for an in-line installation. This particular variant contains a pressure relief facility 'blowing off' when pressure builds up to 50mbar, whilst also includes a 5mbar vacuum feature allowing air into the tank to create a balance should the pressure drop.
