Abstract
A valve assembly for controlling a flow of a coating to a spray head is provided. The valve assembly has a movable needle for closing an opening in a valve seat. The needle has a non-stick outer coating and extends through a needle seal having first and second ends. The first end of the needle seal is disposed inside a seal holder and abuts an interior surface of the seal holder. A spring applies a force to the second end of the needle seal, thereby pressing the first end of the needle seal against the interior surface of the seal holder.
