With increasing global regulations on fuel vapor emissions, vapor recovery fuel nozzles have become essential for safety and environmental compliance at fueling stations. The HYQ-A Series is a premium fuel nozzle designed for vacuum-assisted vapor recovery systems. Featuring an integrated vapor valve, it is certified for use on the world’s most widely adopted vapor recovery systems, including Dresser/Wayne, Wayne®Vac, Gilbarco®, VaporVac®, Schlumberger, and Vacurite.
Around the world, this type of fuel nozzle is known by different names depending on regional standards and environmental regulations. In North America and Australia, it is commonly referred to as a vapor recovery fuel nozzle, while in Canada it is often called a gasoline vapor return nozzle. Across Europe, the term Stage II recovery nozzle is widely used in line with emission control systems. In the Middle East, it may be described as an eco-friendly fuel dispensing nozzle, whereas in Southeast Asia and Africa, names such as fuel vapor return nozzle or low emission fuel nozzle are more commonly adopted.
Although the terminology varies by market, all of these nozzles share the same fundamental purpose: recovering fuel vapors during refueling to reduce emissions, support environmental compliance, and improve operational safety.
Enhanced Safety Features for Reliable Operation
The HYQ-A Series is engineered to provide maximum safety and reliability in high-demand commercial environments:
Pre-Pressure Safety Mechanism: No fuel flow until the system is pressurized, preventing accidental spills
Flow-Lock™ Shut-Off: Automatically stops fuel flow if the nozzle falls or tips, minimizing spills and hazards
Lever Guard Blocker: Prevents the nozzle from being jammed in an open position
Vapor Escape Guard (VEG): Optimizes vapor collection efficiency
Integrated Vapor Valve: Only opens when fuel is flowing, controlling vapor capture precisely
These features ensure safe, spill-free operation and compliance with international fuel handling standards.
Durable Design for Long-Term Use
The HYQ-A Series nozzle is built for exceptional longevity:
Tested for over 1 million cycles, outperforming most nozzles on the market
Soft stainless steel spout provides explosion-proof durability and longer service life than standard aluminum spouts
Reinforced lever guard protects vehicles from scratches
Improved hold-open clip spring extends durability
Internal vapor path requires no replacement parts, reducing maintenance costs
This robust design ensures reliable performance in busy, high-traffic fueling environments.
User-Friendly and Comfortable
Precision flow control ensures accurate dispensing and reduces fuel waste
Two-piece hand insulator offers superior grip comfort for extended use
One-finger hold-open clip simplifies flow rate adjustment (on selected models)
Multiple color options (Red, Green, Black, Blue, Silver, White, Yellow, Gold) allow easy fuel type differentiation and station management
These ergonomic features enhance both customer experience and operational efficiency.
Reliable Performance Across All Climates
HYQ-A Series nozzles are available in standard and low-temperature versions, capable of operating effectively in extreme environmental conditions:
Standard type: -25℃ to 65℃
Low-temperature type: -45℃ to 65℃
This ensures consistent performance in cold climates, such as Northern Europe, Russia, Central Asia, and North America.
