3/2 Pneumatic Interlock Valves (AIVSeries)
Liquip's pneumatic interlock valve provides a pneumatic interlock on API adaptors, vapour adaptors or interlock bars.
The AIV3 3/2 way air valve is used to identify that a hose has been connected to the adaptor for either loading or discharge.
It can also form part of the pneumatic circuit to ensure the tank truck breaks are on, the emergency valve is open and the vapour vents are open before product can flow.
Commonly mounted to API490 series adaptors, VCM450 and GC300 series guard bar.
