Fuel System Components - Tank Vent Valves
Tank vent valves are designed to direct vapors generated during the diurnal cycle. Vent lines from TVVs generally run to carbon canisters. Properly installed, TVVs help protect canisters from liquid fuel.
Perko's TVVs are sometimes referred to as rollover valves (since they offer rollover protection) and as grade vent valves. They also include a over-pressure relief feature.
Mounting options for tank mounted ICVs include flanged (for plastic tanks), threaded (for metal tanks) and swivel (for both plastic and metal tanks).
