Purge / Drain valve Type E-G 028-446 G PC
Within the fuel cell, water emerges as a result of a hydrogen/oxygen reaction; it is drained off by a drain valve.
The oxygen necessary for the electrochemical reaction is delivered by air, so within the fuel cell, nitrogen is accumulated.
Another application of the valve is the control of the cooling agent cycle.
In order to circumvent corrosion by aggressive media such as deionised water, medium-isolated valves are used.
