Diurnal Vapor / Air Valve - DCV

Diurnal Vapor/ Air Valve
• Glass filled black nylon
• Allows for continuous fuel venting vapor out, and make-up air into, fuel tank organically, 24/7, whether engine is idling, throttling or off.
• EPA APPROVED AND COMPLETELY REPLACES THE NEED FOR A CARBON CANISTER.
• Compatible with Ethanol based fuels.
• 5/8" internal diameter hose size

Eliminate the need for a carbon canister. - A cleaner, more practical approach to staying EPA/CARB compliant through better engineering.
1 PSIG diurnal relief pressure valve commonly referred to as a Diurnal Control Valve (DCV) solves many of the issues surrounding carbon canister failure modes like water intrusion, fuel saturation, degradation over time etc. Whether the relief valve is housed in a specially designed EPA deck fill or as an inline diurnal valve component with its own dedicated vent hose and thru hull fitting, they are unaffected by environmental factors. 1 PSIG diurnal relief pressure valves, if mounted “in-line” eliminate the need to use outdated, costly carbon canisters and allow dedicated refueling vapor to escape through the deck fill.
