Check valves include smart valves, which incorporate a low-inertia poppet design with double-tapered O-ring seals to achieve a fast, positive seal in ultra-low-pressure applications. These valves control fluid or gas in low-pressure, low-flow systems. With more than 16,000 possible configurations, these check valves offer a maximum degree of modularity and versatility. Users can create custom valves from stock parts by specifying cartridge size, end fitting, opening pressure, body material, O-ring, and spring material.
