1.Durable material: This check valve is made of quality aluminium alloy, the service life is longer than that of the PP oil valve, and this check valve is more durable and corrosion resistant. 2.Special pushlock design: a oneway bleed valve keeps the fuel tank connected to the original line and prevents fuel from returning to the fuel tank. Its connector is easy to connect and has a push lock function to prevent the hose from falling off. 3.Compact and lightweight: The medium that needs to use the check valve of the fuel line is water, etc. Not suitable for methanol, as it has a corrosive effect on the inside of the product and can lead to product failures. 4.Convenient to installWorking pressure range: 0.2 6. Operating temperature range: 30C to 130C. Opening pressure: 0.2 arrows indicate the position of the inline fuels to the check valve. When connecting the pipe, we can use the arrows to indicate the process.
