Abstract
The present technique provides a system and for improving control of a needle valve in a spray coating device. An exemplary spray coating device of the present technique has a needle valve assembly that controls entry of a fluid to a fluid delivery tip. The needle valve assembly includes an adjustment element that is at least partially located on an exterior of the spray coating device such that the adjustment element is accessible by an operator. The adjustment element may be actuated to improve a seal around the needle so that fluid does not leak from around the needle valve assembly.
