Pisco JKC4-01B0p4IN 4mm x OUT R1/8" Straight 0.4mm Orifice Meter-In Check Valve

This meter-in orifice check valve is designed for unidirectional airflow control. Its 0.4 mm orifice obstructs flow in one direction, allowing free flow in the opposite. The cracking pressure is set at 0.5 bar. The meter-out configuration controls flow from the male threaded port to the push-in fitting, while the meter-in configuration does the opposite. It features a 4 mm push-in fitting on one end and an R 1/8 inch male threaded port on the other. The push-in fitting connects easily to tubing via stainless steel claws. Operating pressure ranges from 1 to 9 bar (14.5 to 130.5 psi), and NBR seals ensure suitability for temperatures between 0 and 60°C (32 to 140 °F). This product is available in the United Kingdom.
