Model ID: DY199
The DY199 Self-Sealing Vapor Recovery Nozzle represents the next generation of emission control technology, specifically designed to eliminate "fugitive emissions" that occur even when the pump is idle. Standard vapor recovery nozzles can sometimes act as open vents for the underground tank, allowing fumes to escape when the nozzle is racked. The DY199 solves this with an integrated Self-Sealing Vapor Valve. This valve remains mechanically closed until the nozzle is securely inserted into a vehicle's fill pipe and the flow is engaged. This ensures the vapor path is only open during the active refueling cycle, maintaining the pressure integrity of the station's underground storage system.
Operational efficiency is matched by user safety. The DY199 features a streamlined, bellows-free design (for vacuum assist systems) or a highly compliant sealing boot (for balance systems) that creates an immediate, airtight interface with the vehicle. This prevents vapor leakage at the fill point, protecting the user from inhaling benzene and other harmful hydrocarbons. Constructed with a heavy-duty aluminum body and a stainless steel spout, the DY199 is built to withstand the abuse of high-volume retail environments while delivering the industry's highest hydrocarbon capture rates.
