Clippard In-Line EV Manifold, Side-Ported Supply, #10-32 15491-1

Invented and patented by Clippard, this deceptively simple design features only one moving part with a mere 0.007" of travel. The spider is an armature spring that undergoes a variety of proprietary processes, including the individual calibration of each spider to its valve. Clippard's experience, quality, and specialized processes surrounding spider technology have led EV valves to become the industry standard for valve life, reliability, response, and extremely low leak rates.
