Model ID: DY233
The DY233 Vapor Extraction Fuel Nozzle is engineered specifically for fueling stations utilizing Vacuum Assist vapor recovery systems. Unlike "balance" systems that rely on the pressure of the tank to push vapors out, the DY233 is designed to work in concert with a vacuum pump located in the dispenser. This active extraction method allows for a significantly lighter and more user-friendly nozzle design, as it does not require a heavy, cumbersome sealing bellow to function effectively.
The core of the DY233's efficiency lies in its integrated vapor valve. This internal valve opens only when fuel is flowing, ensuring that the vacuum suction is applied at the precise moment it is needed to capture escaping hydrocarbons. The vapors are drawn in through the nozzle spout's localized perforations and routed through the coaxial path back to the storage tank. This design captures fumes even without a perfect seal against the car's fill pipe, making it far more forgiving and easier for customers to use. The result is a cleaner forecourt, reduced odor for the customer, and full compliance with environmental air quality regulations.
