Vapor Recovery Breakaway Valve（ Stainless Steel）

Gas Station Vapor Recovery Breakaway Valve, Stainless Steel
Core Differentiation from Aluminum Alloy Version:
- Material Advantage: Made of high-strength stainless steel (vs. aluminum alloy), with superior corrosion resistance (resists harsh chemicals, salt spray, and long-term outdoor exposure without rust) and higher structural strength (handles extreme pulling forces in heavy-duty scenarios).
- Weight & Cost: Slightly heavier than aluminum alloy but offers longer service life in harsh environments; cost is higher than aluminum but lower than all-metal corrosion-prone alternatives.

1. Performance & Parameters
- Thread: M34×1.5 (precise match for gas station vapor recovery pipelines).
- Working Pressure: ≤0.6 MPa (suits vapor recovery system pressure).
- Preset Breakaway Force: 1200–1500N (customizable, balances safety and reliability).
- Medium: Gasoline/diesel vapor, compatible with harsh fuel blends.
- Operating Temperature: -20℃ ~ +70℃ (wider range than aluminum, adapts to extreme climates).

2. Working Principle, Application Scenarios & Usage
- Working Principle:
Internal precision shear structure activates when external force reaches preset value, separating the valve body. Spring-loaded sealing spools at both ends instantaneously block vapor flow, achieving “separation = sealing” within 0.5 seconds.

- Application Scenarios:
① Harsh-environment gas stations (coastal, high-humidity, or industrial areas): Stainless steel resists salt spray and chemical corrosion, outperforming aluminum in longevity.
② Heavy-duty vapor recovery systems (oil depots, large-scale fuel terminals): Higher structural strength handles frequent/intense pulling forces.
- Usage Methods:
1. Installation: Align M34×1.5 threads with pipelines, tighten moderately with a wrench (avoid over-tightening to prevent thread damage).
2. Operation: Automatic separation/sealing during accidental pulling; no manual intervention in normal use.
3. Maintenance: Quarterly inspection—test breakaway/sealing via simulated force. Replace if sealing surfaces show wear or corrosion.

Summary:
- Choose stainless steel if your site is in a harsh environment (coastal, industrial) or requires heavy-duty protection.
- Choose aluminum alloy for standard gas stations in dry climates, prioritizing cost and weight.

Both versions ensure instant sealing during breakaway, but material differences guide selection for longevity and scenario-specific needs.
