2 way pressure relief valve does not need an unloader

by CONRAD

If a compressor switch says it has 2 way pressure relief valve, does it mean that it does not need an unloader.


A compressor switch I was looking at said it had 2 way pressure relief valve. Does this mean that this is the unloader?

2 way pressure relief valve

Conrad, while I do not have a compressor with a 2 way pressure relief valve, and since you refer to a compressor pressure switch (I think) in your question, here is what I found from the manufacturer of one compressor 2 way pressure relief valve.

"pressure switches are designed for the control of small electrically driven air compressors. Unloader models feature a small valve that opens at shutoff, releasing air pressure from the compressor head."

I don't have the specifications of the one you saw, but yes, if you acquire a pressure switch with this attribute, it appears to work as the unloader valve as well.
