ABSTRACT:
A compression valve assembly includes a valve cage having a stem at a first end and an annular skirt at a second end. The skirt is provided with a slidable surface. A relief valve is adapted for selectively blocking fluid flow through the valve cage. A cup includes an annular rim and a base. The rim is provided with a slidable surface. A spring biased agaist the relief valve is selectively compressed as the cup rim is slidably received over the skirt by a measured axial load provided by a preloading means. The cup is secured to the valve cage and the axial load is removed.
