Relief Valve, PS2020 #07F901

The relief valve is located on the side of the air compressor's pressure switch. If your relief valve is attached to your switch by inserting through a hole on the side bracket, then this is your style. Order this if your valve is broken.

If this valve leaks continuously after it shuts off, don't order this, order a check valve instead. It backfeeds this valve when defective giving a false sign that the relief valve needs to be replaced.
