All York or similar OBA folks.. I am looking for an in line "unloader" / check valve. Found several, but I don't know if it is what I think it is. example: amazon New In Line Check valve for air compressor 1/2" FPT x 1/2" FPT - Air Compressor Accessories - Amazon.com
Is this simply an In Line check valve (1/2" to 1/2") with the side port for the pressure relief (I would use a small copper air muffler)
