A/C compressor makes noise

Picture of the valve? York compressor ? What happened to the original compressor..what was reason for R&R? Was it R12 or previously converted to R134a.? Did you flush and evacuate system prior to assembly of current system ? and what other components did you replace? You say it blows cold but what are pressures and vent temps along with ambient temp. ?

This will all be helpful info . I know of no valve at the compressor that will cause major if any noise unless you are talking about an isolation valve for repair / charging/ isolating compressor.

What method did you use to charge ? Gauges hopefully or at least precise weight ?
