What is the function of the start valve on a 21 gal Central Pneumatic compressor. Can it be removed and replaced with a plug to stop the air from coming out.

Thanks for the post Nick,

No, this isn't technically necessary for the unit to start and operate. This is a "cold start" valve and it simply dumps the excess air from the pump head to make starting easier, especially in colder climates.

You can plug it up and it should operate. The unit has an unloader valve (on the pressure switch) that dumps the air in the line so it doesn't start with pressure in the line. As long as the unloader valve is operating like it should, you shouldn't have any problems.
