Product Description

FUEL CHECK VALVE

Appilication

The one-way valve is installed in the engine compartment. The temperature in the engine compartment can reach as high as 98 °C during the long-distance driving. Therefore, the selection of the one-way valve is important. At present, most common one-way valves on the market are at room temperature, and the relatively high temperature resistance is only 80 ℃. In order to avoid the car failure during long-distance driving, please choose BBTUS high-temperature-resistant one-way valve. High quality and temperature resistance up to 135 °C.

Material

The shell material is PA66, and the Diaphragm material is VITON,the spring material is SUS316L.Normal performance under -25 ℃ to 135 ℃, Strong resistance to High Temperature and Corrosion. One-way valves are commonly used in brake boosters - air conditioning damper ducts - exhaust valve ducts and wiper sprinkler ducts on automobiles. The one-way valve is widely used and can be reasonably used according to individual needs.

How to use

To connect the liquid pipeline, it is necessary to bind the interface with a clamp

I bought these to use in line with tubing which goes from the sink soap dispenser pump down into a container of dish soap which sits in the sink cabinet. Without the check valve I could get the tubing primed and it pumped a little but once I stopped using it the soap slowly dropped back down into the soap container. But with the check valve installed the soap stays in the tubing so that whenever I press the soap pump handle I get dish soap dispensed. It removed the difficult task of trying to fill the soap dispenser bottles which were screwed up under the sink. The bottles are no longer under the sink - just tubes running down into the larger dish soap bottle which is very easily replaced. I realize that this was not the original intent for these check valves but they work well for my use which I found from a kind soul who posted a video on YT..

I needed these for the kaboom chlorine dispenser to prevent the chlorine from back flowing to the fill valve. Needless to say, it did the job.

My motorcycle need vacuum applied to the fuel petcock to keep running. It is a safety feature to prevent fuel flow when the engine is off. I was experiencing a loss in vacuum when going up hills under load. The bike would shut off when this happened. I would have to idle the bike for a minute and then I would be able to drive until I came up to another hill and the same thing would happen. Installing this valve corrected the issue! It saved me a lot of headaches. Thank you!

These little guys work well and hold vacuum with little leakage. They are superior to similar check valves I have purchased at the auto parts store.
