Abstract
A method of making a valve (62) that has a poppet valve member (100) biased by a spring (110) toward a closed position against a poppet valve seat (90). The spring acts between the poppet valve member and a spring seat (120) and applies a predetermined force to the poppet valve member. The method comprises the steps of providing a valve housing (70) having a chamber (72); inserting into the chamber in sequential order the poppet valve seat (90), the poppet valve member (100), the spring (110), and the spring seat (120); applying a force to the spring seat to compress the spring a predetermined amount; and securing the poppet valve seat and the spring seat to the housing (70) while maintaining the spring compressed the predetermined amount.
