What does a AC compressor relief valve do?
Pressure relief valves are used to control and limit the pressure build-up in a system. If pressure exceeds the amount allowed by the pressure relief valve, the pressure relief valve will automatically open and release air until the pressure is reduced.
How do you check a compressor safety valve?
How do you test a air compressor safety valve?
- Step 1 – Use the Air Compressor. In order to test the release valve it first needs to be under pressure.
- Step 2 – Locate the Release Valve. Inspect the tanks of the air compressor.
- Step 3 – Test. Grip the release valve with the wrench and pull straight out.
How to fix a pressure relief valve on an air compressor?
Fill your compressor with some air. Locate the pressure relief valve and its ring. Pull the ring carefully. See if you can detect air venting. Push the end of the pin to shut off the air flow. If air vents out of the valve, then it’s good. If not, then you should take measures.
When does a pressure relief valve start blowing air?
Here the pressure relief valve starts blowing air as soon as it reaches the normal cut out pressure. This will happen if your pressure switch is damaged or is unable to work. At this point, it’s good that your pressure relief valve is working. But you have to keep an eye on the pressure gauge in this case.
What happens when a compressor pressure switch fails?
When pressure switch fails, your compressor plunges in more and more air. At that point, your second safety measure, the pressure relief valve kicks in. Before the pressure reaches a dangerous level, your pressure relief valve will blow open and will start venting air into the atmosphere.
Is it safe to use a pressure relief valve?
During the testing and fixing of pressure relief valves, you must take some safety measures. Keep an eye on the pressure gauge and don’t let a high pressure to build up. Follow these measures and you’ll be safe enough for the air compressor use. A small part like the pressure relief valve plays an important role in air compressor safety.
How to detect an air compressor pressure relief valve problem?
To detect an air compressor pressure relief valve problem, you have to look out for certain symptoms like air bleeding, pressure deficit, etc. Moreover, you have to keep a close eye towards your pressure gauge.
Here the pressure relief valve starts blowing air as soon as it reaches the normal cut out pressure. This will happen if your pressure switch is damaged or is unable to work. At this point, it’s good that your pressure relief valve is working. But you have to keep an eye on the pressure gauge in this case.
When to replace the safety valve on an air compressor?
The safety valve pops open to relieve excessive air pressure if the pressure switch fails to shut off the air compressor at the cut-out pressure setting. Replace the safety valve if it leaks or pops open at normal operating pressure. The pressure switch turns the air compressor pump on and off to regulate tank air pressure.
