Pisco JKL8-02B1p9IN 8mm x OUT R1/4" Angled 1.9mm Orifice Meter-In Check Valve

This one-directional check valve regulates constant airflow with a 1.9 mm orifice that restricts flow in one direction while allowing free flow in the opposite. Its cracking pressure is 0.5 bar, and its meter-in configuration controls flow from the male threaded port to the push-in fitting port. The valve features a push-in fitting on one end for easy tubing connection and an R 1/4" male threaded port on the other. The push-in fitting utilizes stainless steel claws for secure tubing retention. The valve operates within a pressure range of 1-9 bar (14.5-130.5 psi) and a temperature range of 0-60°C (32-140 °F) thanks to NBR seals, ensuring no freezing. This valve is available in the United Kingdom.
