Everything You Need to Know About Aluminum Check Valves
Where is a check valve located?
Check valves are used in many different applications. For example they are often placed on the outlet side of a pump, to protect the pump from backflow.
Also question is, are check valves necessary?
The check valve prevents stored energy from making its way back into the pump, an especially important task when there is stored energy in the accumulator and the pump is not even running. Energy stored in an accumulator can be dangerous or damaging and must be controlled for hydraulic systems to be safe and reliable.
Furthermore, how can you tell if a check valve is bad?
For example, check valves that are starting to fail will vibrate or make a noise indicating that the valve has broken. A strange noise can also be a sign of ‘water hammer’ which is a high-pressure surge that occurs when the fluid comes to a stop or changes direction, often causing the disc to slam into the valve.
Also Know, what happens when a check valve goes bad?
When the check valve is not working correctly, the operation of the brakes becomes much more difficult. Specifically, the pedal goes from smooth and soft to aggressive and very difficult to press down. This is due to the excess pressure inside the master cylinder, which the check valve is designed to regulate.
