Check Valve

Fuel station angle check valve is designed to prevent reverse flow in fuel dispenser and storage-tank piping systems. The valve’s high-strength cast body provides reliable corrosion resistance when handling gasoline and diesel, meeting the operational requirements of fuel station environments.

The angle-body configuration features a male threaded connection at the bottom and a female threaded connection at the side for straightforward installation in underground fuel lines and dispenser flexible-connector assemblies. The check valve can be installed beneath a fuel dispenser, between the fuel line and flexible connector, at a storage-tank outlet, or at the outlet of a submersible turbine pump. Suitable for operating temperatures from −40°C to +70°C, the angle check valve is used in gasoline and diesel transfer systems at fuel stations and oil depots.

    Applications
    • Backflow prevention: The angle check valve allows fuel to flow in one direction and prevents line drain-back after shutdown, helping avoid pump damage caused by dry running.
    • Metering stability: By preventing reverse fuel movement, the valve helps avoid fuel dispenser measurement drift and supports accurate fuel metering.
