How is the pressure relief valve in an air conditioner used?
Automotive A/C Parts. The pressure relief valve is used in the auto air-conditioning compressor to prevent. unusual pressure build-up within a system by opening it’s valve when the internal fluid. pressure starts to exceed the preset pressure level and close it’s valve when the. internal pressure decrease to the preset pressure level.
When to open the compressor pressure relief valve?

What happens when a pressure relief valve blows?
Before the pressure reaches a dangerous level, your pressure relief valve will blow open and will start venting air into the atmosphere. Normally, two things might happen due to a pressure relief valve problem. Your PRV might blow before reaching the pressure cut out or it might not blow at all.
Where is the high pressure relief valve on my car?
On my car, there is no red cap. But it looks like a fitting held in place by the snap ring with a slot (under the red cap) that you place a flat head screwdriver to open the drain. This is from a quick look with a quick conjecture. Just taking a guess here. Orientation of where this sits when the compressor installed supports my guess.
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.
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.
