Rolair 131B Pilot Unloader Valve

Works well, was fairly straightforward to adjust to my desired settings. This compressor is used to fill a 200 gallon stationary bulk tank as needed, and runs for relatively short periods of time about once a week. This valve has performed flawlessly in the time weve been using it.

My compressor bit the dust... I replaced this part, the regulator, oil, air filter, spark plug, muffler, two pressure gauges ... and everything is purring again!

as described

Works perfect no complain about it.

I ordered this fro my Rolair Compressor, the input was incorrect, however, i was able to swap the main body with my defective unit and worked great!

Great item
