The valve is designed to be flexibly installed, using a spring-based actuation technology, which allows Eaton to accommodate different opening pressure requirements with the same valve
20011130 · The valve-regulated version of this battery system, the VRLA battery, is a development parallel to the sealed nickel/cadmium battery that appeared on the market shortly after World War II and largely replaced lead-acid batteries in portable applications at that time. These batteries are characterized by immobilized electrolyte that allows an
Eaton Battery Vent Valves are designed to enable rapid overpressure release in an electric vehicle battery pack. Battery packs are becoming progressively more powerful and create more heat with stricter ingress
2024614 · HOW DOES IT WORK? Properly designed venting systems provide protection from contaminants along with pressure equalization during normal operating
202093 · Dual-stage venting provides an effective solution to the unique challenges of EV battery packs. The first stage, passive venting, handles gradual changes in
20231122 · Discover the working principle of Valve Regulated Lead Acid (VRLA) batteries: Basic Operation: VRLA batteries operate on the principle of electrolysis. Within the sealed battery, two lead plates immersed in a sulfuric acid solution facilitate a chemical reaction. One plate is coated with lead dioxide, while the other is made of spongy lead.
Battery limits are clearly marked in the P&ID and Plot plans. For each unit, there will be separate battery limits. Refer to Fig. 1 Battery limits are usually provided with lots of valves, spectacle blinds, drains, etc. In general, a three-way support restraint (Rest+Guide+Line Stop) is usually provided near the battery limit so that the
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

VRLA battery has a pressure relief valve that activates when the battery starts building pressure of Hydrogen gas. This is generally a result of being recharged at excessive voltage, typically greater than 2.30 volts per cell. Valve activation allows some of the gas or electrolyte to escape. As a result, the overall capacity of the battery
2024624 · Among the many steps in EV battery lifecycle, three rely on control valves: battery slurry production, filling, and battery recycling. Understanding the vital nature of
2023223 · Eaton has introduced a new 3-in-1 battery pack vent valve for EV batteries. The valve is capable of three key functions, including a battery case leak-check
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
202437 · VRLA battery (valve-regulated lead-acid battery) is sealed or regulated by a valve where the electrolyte is immobilized in an absorbent separator or in a gel. VRLA batteries have rubber plugs that seal each cell.
2022111 · Typically, the valve-regulated lead–acid (VRLA) battery (Rand, 2009) has attained important advancements in terms of specific energy, specified power, and
20141210 · VRLA Battery Cut View. When charging is done, two things may happen: 1. the electrolyte may boil and produce too much pressure and/or 2. the gas build up may be too quick for recombination with the water. To regulate these events, a one-way pop-off valve is incorporated into the battery body which only opens when the pressure builds up.
