Description
Perko Tank vent valves are required for vessels manufactured for many offshore markets and are a growing part of fuel safety and environmental protection.
They are designed to direct vapours generated during the diurnal cycle to control the escape of hydrocarbons to the atmosphere.
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 an over-pressure relief feature.
There are multiple mounting styles to suit plastic and metal fuel tanks.
Flanged valves match the SAE 5-bolt level sender flange. Gasket is not included.
Threaded valves mount with a 1″ NPTF thread.
