Safety Breakaway Valve（M42X1.5）

1. Performance Parameters
- Material System：
- Housing: Aluminum alloy (lightweight, resistant to gasoline/diesel corrosion);
- Thread Component: Stainless steel (M42×1.5 specification, ensuring connection strength and wear resistance);
- Internal Parts: High-strength fiber-reinforced plastic (impact-resistant, self-lubricating, maintaining internal structural stability);
- Seals: PU (polyurethane) + NBR (nitrile butadiene rubber) (fuel-aging resistant, instantaneous sealing during separation).
- Specification Parameters：
- Thread: Fixed end M42×1.5 external thread, adaptive end optional internal/external thread;
- Breakaway Force: 1200-1500N (customizable, balancing safety redundancy and triggering reliability);
- Working Pressure: ≤0.6 MPa, Applicable Medium: Gasoline, Diesel, Working Temperature: -20℃~+60℃.

2. Working Principle & Scenarios
- Working Principle：
The valve integrates a *precise shear separation structure*. When the external force (such as violent dragging of the nozzle by a vehicle) reaches the preset value of 1200-1500N, the aluminum alloy housing and the M42×1.5 stainless steel thread component separate quickly, and the internal PU/NBR seals block the fuel channel simultaneously, achieving “breakaway = sealing, no leakage”.
- Application Scenarios：
M42×1.5 specification dispenser-nozzle high-pressure connection pipelines in gas stations, designed to prevent pipeline breakage and large-scale fuel leakage caused by violent dragging, protecting equipment and on-site safety.
