544 Series IntelliSwitch IIv

Electronic switchover without integral pressure regulation
544B004-01-001 shown

The electronic 544 Series IntelliSwitch™ IIv is used to monitor, control, and switch the flow of gas from cryogenic or high pressure cylinders from either of two independent sources. It provides the intelligence and switching capacity of an IntelliSwitch system without an integral regulator.

The outlet pressure will be equal to the pressure in the side selected and will vary or decrease as that source pressure varies or decreases.
