Products Description
1. Overview & Applications
The NGV2 Receptacle (Fill Valve) is an internationally standardized fueling connection interface engineered specifically for Compressed Natural Gas (CNG) vehicles requiring high flow rates. Unlike standard passenger car connections (NGV1), NGV2 profiles are optimized to handle high volumetric delivery, drastically reducing fueling downtime for large-capacity fuel storage systems.
Primary Applications: Heavy-duty commercial trucks, transit buses, long-haul freight haulers, and municipal utility vehicles equipped with high-capacity CNG cylinder arrays.
2. Technical Specifications Comparison
| Feature / Specification | NGV1 Standard (Light Duty) | NGV2 Standard (Heavy Duty) |
|---|---|---|
| Primary Vehicle Type | Passenger Cars & Light Duty Vans | Buses, Heavy Trucks & Commercial Fleets |
| Flow Capacity | Standard / Low Flow | High Flow / Fast Fill (Up to 3x NGV1) |
| Working Pressure | 200 bar (20 MPa) / 250 bar (25 MPa) | 200 bar (20 MPa) / 250 bar (25 MPa) |
| Standard Compliance | ANSI/AGA NGV1, ISO 14469-1 | ISO 14469-2 / ISO 14469 profile |
| Internal Check Valve | Single / Double Sealing Options | Heavy-duty high-flow non-return valve |
3. Core Mechanical Features
High-Flow Geometry: Large internal bore minimizes pressure drops and thermal buildup during rapid high-pressure gas transfers.
Positive Locking Mechanism: Standardized profile ensures secure jaw engagement from the NGV2 nozzle, preventing accidental disconnection under extreme pressure.
Integrated Non-Return Check Valve: Built-in check valve closes automatically when fueling disconnects, preventing backflow from vehicle storage cylinders.
Corrosion-Resistant Materials: Fabricated from high-grade stainless steel (e.g., 316SS) or treated alloys to withstand harsh environmental conditions.
Safety & Maintenance Best Practices: Always keep the protective dust cap secured when the receptacle is not in use. Inspect O-rings and sealing faces periodically for wear or debris.
