Dual-Thread Plated Angle & Anti-Siphon Valve for Fuel Suction Systems

Dual-Thread Plated Angle & Anti-Siphon Valve for Fuel Suction Systems

Reliability in fuel delivery and storage systems is critical for operational safety. The HBJSF-40 Series Angle Check Valves inherit the classic French design, enhanced with unique plated surface treatment and optimized valve cap construction, providing long-lasting corrosion resistance and vibration durability. Whether for retail fuel stations, industrial storage tanks, or commercial fleets, this valve ensures secure fuel system performance.

Global Recognition and Alternative Names
Depending on region and industry, these valves are known by various names:
Americas: “angle check valve” or “suction line safety valve.”
Europe & UK: “elbow non-return valve” or “fuel one-way valve.”
French-speaking regions / former colonies: “vanne anti-retour français.”
Functional / Safety Term: “anti-siphon valve”, highlighting its role in preventing accidental siphoning from storage tanks
With a dual-threaded inlet (2” male + 1.5” female), the HBJSF-40 can connect flexibly to various pipeline systems, simplifying installation.

Key Features and Advantages
Dual-Threaded Inlet: Compatible with multiple tank bung fittings for quick installation.
Spring-Loaded Poppet: Ensures reliable closure even in high-vibration or intermittent operation conditions.
Durable Seal Materials: Buna-N disc (optional Viton) offers long-lasting chemical resistance.
Plated Surface Treatment: Body and valve cap are plated for enhanced corrosion protection and easy visual inspection.
Maintenance-Friendly Design: Single-poppet structure allows fast cleaning, inspection, or disc replacement.
Operating Conditions: Recommended for suction lines with pressures up to 34 ft of head (~15 psi).

Global Applications
Africa & Asia: Commonly used in former French colonial fueling stations, providing reliable anti-siphon protection.
Europe & North America: Industrial suction systems adopt HBJSF-40 valves to maintain long-term fuel line stability.
Japan & Other Asian Markets: Dual-thread inlet simplifies adaptation to mixed-thread NPT/BSP pipelines.
Worldwide Operators: The HBJSF-40 is a preferred solution for preventing accidental fuel siphoning.

Why Choose HBJSF-40
Every HBJSF-40 valve undergoes rigorous factory testing to ensure consistent performance. The combination of French design heritage, innovative plated surface, optimized valve cap, spring-loaded poppet, and anti-siphon functionality makes it an ideal choice for fuel suction systems, industrial storage tanks, and commercial fleet operations.
