Non Valve Purpose and function Prevents fuel from being sucked back into the tank. The valve remains in the fuel line to maintain a steady flow and protect the fuel system, including the pump, from backflow and pressure fluctuations. Suitable applications and compatibility Works with both and low pressure fuel systems. Suitable for diesel, bio/vegetable oil, paraffin/kerosene, and other compatible fuels. Effective performance Efficient design stops backflow, stabilizes fuel supply, and helps preserve overall system integrity and reliability. Material and durability Constructed from aluminum alloy for corrosion resistance and dependable performance in harsh operating conditions. Key benefits Backflow prevention to maintain consistent fuel pressure, compatibility with multiple fuel types, durable aluminum alloy construction, and reliable operation in demanding environments. Use scenarios Automotive or fleet diesel installations: in the fuel line between the tank and pump to prevent backflow when the engine is off or during lowflow conditions. Biodiesel or vegetable oil fuel systems: suitable for lines using biodiesel blends or vegetable oil, helping maintain steady flow and system integrity. Portable power and heating equipment: in fuel lines of generators or heating systems to prevent siphoning and ensure reliable startup and operation.
