The Eaton 3-in-1 Battery Vent Valve is the first valve on the market that is capable of three unique functions, including a battery case leak-check mechanism and passive and active venting to provide overpressure relief for a vehicle’s battery pack.

Eaton also developed the tool to actuate the leak check mechanism at customer assembly lines, allowing for testing through pressurization or a vacuum.

Its spring-based actuation technology allows us to accommodate flexibility to different opening pressure requirements while keeping the same valve design to drive economies of scale.

• Eliminates the need to remove the valve before checking the battery pack assembly for a leak.
• The valve’s proven resealing technology allows our customers to specify very low opening pressures and 100% functional testing in comparison with the conventional burst-valve technology commonly used in the market today. 
• Features a low-flow breathing mode that allows air to move through porous material to normalize pressure during regular operation.
• Reduces complexity for battery pack manufacturers while ensuring a sturdy connection that stays in place.
• Eaton’s 3-in-1 battery vent valve can be precisely and flexibly designed to meet specific opening pressures and optimize venting.
