Pisco JKL4-01B1p9IN 4mm x OUT R1/8" Angled 1.9mm Orifice Meter-In Check Valve

This meter-in elbow orifice check valve is a fixed airflow controller designed for one-directional flow. Its 1.9 mm orifice allows flow in one direction and obstructs it in the opposite direction, providing free flow. Cracking pressure is at 0.5 bar. The meter-in configuration controls flow from the male threaded port to the push-in fitting port. It features a 4 mm push-in fitting on one side and an R 1/8 inch male threaded port on the other, allowing easy connection to tubing. Flow is metered from the push-in fitting port to the male threaded port. The operating pressure range is 1 to 9 bar (14.5 to 130.5 psi), and NBR seals ensure suitability for temperatures from 0 to 60°C (32 to 140 °F), excluding freezing. Available in the United Kingdom.
