Deploying the right dispensing equipment is paramount for operational efficiency. The TDW-7H Automatic Nozzle is engineered to eliminate common bottlenecks in fluid transfer, offering a suite of features that directly address the daily challenges faced by high-volume fueling facilities.
Ergonomic Excellence: The carefully sculpted handle reduces hand strain, allowing operators to manage continuous dispensing cycles without fatigue.
Acoustic Dampening: Internal fluid dynamics are optimized to reduce the harsh hissing sounds typically associated with high-pressure fueling, creating a safer auditory environment.
Spill Mitigation: Advanced sensory mechanisms instantly detect fluid levels, safeguarding your facility against hazardous overflows and costly cleanup procedures.
Streamlined Maintenance: Designed with modularity in mind, allowing your on-site technicians to perform rapid component swaps without specialized diagnostic tools.
The physical construction of dispensing equipment dictates its lifespan in harsh commercial environments. We have selected materials that offer exceptional resistance to both mechanical wear and chemical degradation.
Rugged Aluminum Core: The main body is cast from high-strength aluminum, providing a solid, unyielding foundation that withstands the physical impacts of daily drops and rough handling.
Advanced Polymer Protection: The lever and lever guard are molded from Duratuff, a specialized high-impact plastic that remains warm to the touch in freezing conditions and resists shattering.
Chemical-Resistant Internals: Core sealing components utilize a strategic combination of Buna-N and Viton, ensuring absolute integrity against aggressive fuels and preventing microscopic leaks over time.
Extreme Climate Resilience: Engineered to perform flawlessly in punishing environments, maintaining perfect mechanical fluidity from a freezing -45℃ up to a blistering 55℃.
Time is a critical metric in fleet management. This nozzle is specifically calibrated to maximize fluid delivery speeds while maintaining absolute control over the dispensing process.
High-Volume Throughput: Capable of delivering a massive 80-120 L/min, drastically reducing the time heavy-duty trucks and buses spend at the pump.
Foam Reduction Technology: The internal geometry creates a uniquely smooth spray pattern. You can visually observe the reduction in diesel foaming, which prevents frustrating false shut-offs and allows tanks to be filled to maximum capacity on the first attempt.
Consistent Flow Rates: Even at the minimum flow rate of 20 L/min, the delivery remains steady and predictable, ensuring accurate metering for smaller utility vehicles within a mixed fleet.
Risk management is built into the core architecture of the TDW-7H Automatic Nozzle. Every mechanical action is designed to protect the operator, the vehicle, and the surrounding environment.
Hyper-Responsive Shut-off: The 0.1-second auto shut-off sensibility acts as an immediate fail-safe, instantly halting flow the millisecond fuel reaches the sensor port.
Anti-Tilt Lock Mechanism: If the nozzle is accidentally dropped or points upward, the internal safety lock engages automatically, physically cutting off the fluid pathway to prevent catastrophic spills.
Two-Stage Lever Design: Requires a deliberate, intentional squeeze to initiate flow, completely eliminating the risk of accidental discharge during handling or holstering.
Dash-Pot Action: As the valve closes, the built-in dash-pot mechanism cushions the internal components. Instead of a violent metallic clank, you hear a muffled, controlled thud, which absorbs line shock and protects your facility's expensive piping infrastructure from water hammer damage.
Complex equipment leads to extended downtime. We prioritized intuitive operation and straightforward maintenance protocols to keep your dispensing lanes active and profitable.
Effortless Engagement: The innovative dual-poppet design breaks the pressure vacuum in two stages. This means the operator only needs a fraction of the grip strength to open the nozzle, even when the station's pumps are running at maximum 0.34 Mpa pressure.
Hands-Free Operation: A robust 3-notch hold-open clip allows users to securely set their desired flow rate with a single finger, freeing them to perform other essential vehicle checks during the fueling process.
Rapid Spout Replacement: The spout assembly is entirely modular. If damaged by a drive-off, maintenance personnel simply remove three accessible screws to swap in a new 30mm or 28.7mm spout, returning the pump to service in minutes rather than hours.
A superior dispensing nozzle must integrate flawlessly with your existing infrastructure and adapt to diverse regional fuel standards without requiring costly retrofits.
Universal Threading: Available with standard 1" NPT or BSP inlets, ensuring a perfect, leak-free union with hoses across North American, European, and Asian markets.
Versatile Spout Sizing: Ships with a choice of a common 30mm spout for standard heavy-duty applications, or a 28.7mm small spout to accommodate specific regional tank filler necks.
Multi-Fuel Capability: Thoroughly tested and certified for use with a broad spectrum of media, including standard diesel, kerosene, gasoline, and modern ethanol blends (up to 10%).
Fleet Flexibility: Whether servicing a municipal bus depot, an agricultural cooperative, or a high-traffic commercial truck stop, this nozzle adapts to the specific flow requirements of the vehicles being serviced.
Procurement decisions require absolute confidence in product reliability and regulatory compliance. Our manufacturing processes are governed by uncompromising quality control standards.
Rigorous Pre-Shipment Testing: Every single nozzle undergoes a 100% wet-test protocol on our assembly line to verify the 0.1-second shut-off sensibility and structural integrity before it is packaged.

To assist your engineering and procurement teams in their evaluation process, we have compiled detailed answers to the most critical technical inquiries regarding the TDW-7H Automatic Nozzle.
1. How does the dual-poppet design function under high-pressure commercial pump systems?
The dual-poppet valve opens in two distinct stages. When the operator squeezes the lever, a smaller primary valve opens first to equalize the pressure across the main valve. This drastically reduces the physical force required to open the main fluid pathway, allowing smooth, one-handed operation even at the maximum working pressure of 0.34 Mpa.
2. Can the spout be replaced on-site without taking the dispenser offline for extended periods?
Yes. The spout is secured by three easily accessible screws at the base of the nozzle body. A station technician can unthread these screws, remove the damaged spout, insert a replacement (either 30mm or 28.7mm), and secure it in under five minutes, requiring zero specialized tools or extended lane closures.
3. What makes this nozzle suitable for extreme cold weather down to -45℃?
The resilience in freezing temperatures is achieved through the use of aerospace-grade Buna-N and Viton seals, which maintain their elasticity and prevent shrinkage-induced leaks. Additionally, the Duratuff lever guard remains impact-resistant and thermally neutral, preventing the plastic from becoming brittle and shattering in sub-zero conditions.
4. Does the nozzle support high-ethanol blend fuels?
The TDW-7H is fully compatible with standard gasoline, diesel, and kerosene, as well as ethanol blends up to 10%. The internal Viton seals are specifically chosen for their high resistance to the corrosive nature of ethanol, preventing degradation and swelling over long-term exposure.
5. How does the dash-pot mechanism prevent line shock during rapid shut-off?
When the 0.1-second auto shut-off triggers, the valve does not slam shut instantaneously. The built-in dash-pot acts as a hydraulic shock absorber, slightly decelerating the valve's final closing millimeter. This smooths out the sudden halt in fluid momentum, effectively mitigating water hammer effects that could otherwise rupture hoses or damage internal dispenser meters.
