Pisco JKC4-01B0p7IN 4mm x OUT R1/8" Straight 0.7mm Orifice Meter-In Check Valve

This single-directional air check valve controls airflow with a 0.7 mm orifice, opening in the direction of flow while obstructing it in the opposite. Its cracking pressure is 0.5 bar. The "meter-in" configuration restricts flow from the male threaded port to the push-in fitting, while the "meter-out" configuration does the reverse. It features a 4 mm push-in fitting on one end and an R 1/8 inch male threaded port on the other, providing easy tubing connection with stainless steel claws. Its operating pressure ranges from 1 to 9 bar (14.5 to 130.5 psi), and it withstands temperatures from 0 to 60°C (32 to 140 °F) thanks to NBR seals. This product is available in the United Kingdom.
