The HAIBO-41A ZVA Type fuel nozzle represents a new generation of automatic fueling solutions, designed to optimize fuel delivery, safety, and vapor management at modern service stations. Engineered for dispensers with integrated vapor recovery control, this nozzle minimizes emissions while ensuring reliable, efficient operation in a wide range of conditions.
Globally, this type of fuel nozzle is known by different names, influenced by regional standards, market practices, and environmental regulations. In China and Taiwan, it is commonly referred to as a vapor recovery fuel nozzle, while in Europe and North America it is often described as a fuel vapor return nozzle. In Australia and New Zealand, the term automatic fueling nozzle is widely used. Across the Middle East and North Africa, it is typically identified as a Stage II vapor recovery nozzle, and in Germany and other EU countries, it may also be recognized as a ZVA-type eco-friendly fuel nozzle.
Although the terminology varies across regions, all of these nozzles serve the same essential purpose: capturing fuel vapors during the refueling process to improve operational safety and reduce environmental impact.
Key Safety and Operational Features
The HAIBO-41A integrates several advanced mechanisms to protect users and equipment:
Automatic Shut-Off System: Venturi-controlled shut-off prevents overfilling, protecting vehicles and fuel tanks
Integrated Vapor Recovery Valve (GRV): Opens only during fueling and closes automatically when fueling stops, ideal for shared vacuum pump systems
Optional Proportional Valve (GRVP): Allows fine adjustment of vapor recovery relative to fuel flow
Two-Stage Lever Latch with Removable Pin: Enhances operational safety and convenience
These features make the nozzle reliable for high-traffic commercial fueling environments while reducing spills and vapor loss.
Durable, Long-Lasting Construction
The HAIBO-41A nozzle is built for heavy-duty performance with premium materials:
Body: Aluminum for lightweight durability and corrosion resistance
Suction Inlet & Internal Components: Aluminum, stainless steel, brass, POM, and PEEK for high wear resistance
Seals: NBR, PU, FKM for temperature and chemical resilience
Grip Cover & Scuff Guard: PVC for comfort and anti-slip handling
Product Sleeve EK043: Polyurethane (PU) for impact protection
This robust construction ensures consistent operation and reduces maintenance requirements.
Wide Temperature Range and Fuel Compatibility
Operating Temperature: -20°C to +55°C
Fuel Compatibility: All standard gasoline, including ethanol blends up to E85 (not suitable for pure alcohol, water, or solvents)
Available Colors: Red, Green, Black, Blue, Silver, White, Yellow, Gold
These specifications make HAIBO-41A adaptable to diverse climates and fuel types worldwide.
Enhanced User Experience
Ergonomic Design: Two-piece hand insulator for comfortable, long-duration handling
Easy Flow Control: Automatic shut-off and vapor recovery functions synchronize for intuitive use
Flexible Configuration Options: Optional proportional vapor recovery valve and lever latch designs allow customization for station requirements
These features improve operational efficiency and increase customer satisfaction.
