check valves 100 Series 0 to 25 psig Check Valves How it Works Open Full flow passages offer minimum restriction to flow. Spring is completely removed from flow path Closed As the inlet supply pressure decreases, a light spring closes the poppet, positioning the knife-edge automatically in line of contact sealing against the o-ring. The impression of the knife edge is limited by a metal-to-metal seat, which carries the reverse pressure load and serves to prevent sticking of the o-ring. Features & Benefits Low pressure • Lightweight check valve for pressures to 25 psig. Ultra-sensitive • Unique design allows flow with minimum pressure differential. Cracking pressure is 4½ HO maximum. Positive sealing • Unique knife-edge on the poppet positions snugly to provide zero sealing even with extremely low pressure. Zero leakage • Compact, easy installation. Efficient, inline design reduces size and weight. The valve can be mounted in any position.
