<p>A valve (32,40) is assembled by telescoping a first body component (50,71) relative to a second body component (51,72) until reaching a relative position that corresponds to a predetermined valve operation parameter, such as a valve opening pressure. The first body component (50,71) is then fixed with respect to the second body component (51, 72) at the relative position, such as by laser welding. The present invention finds potential application as a cartridge valve for a pump (11), such as a pressure relief valve (32) and/or pressure reduction valve (40). The relative positioning control over the body components (50,51,71,72) de-sensitizes valve operation from variations in valve components, such as variations attributable to geometrical tolerances. <IMAGE></p> |
