Abstract
A method of configuring a valve comprised of a valve seat, a valve stem, a valve guide, and a relief compression spring. The method comprises calculating a compression force required to move the valve stem relative to the valve seat, using that calculated force to move the valve guide into a desired position, then crimping the valve guide to the valve stem at that desired position. The method also comprises attaching a check compression spring to the valve stem at a location inside the valve guide, installing the valve in a test stand to measure the actual pressure required to achieve the desired rate of fluid flow and forming the valve seat using metal injection molding.
