Pisco JKL4-01B1p8IN 4mm x OUT R1/8" Angled 1.8mm Orifice Meter-In Check Valve

This meter-in elbow orifice check valve controls unidirectional airflow. Its 1.8 mm orifice restricts flow in one direction while allowing free flow in the opposite. Cracking pressure is 0.5 bar, and the flow is controlled from the male threaded port to the push-in fitting port. One side features a 4 mm push-in fitting for easy tubing connection, while the other has an R 1/8 inch male threaded port. The valve can handle pressures from 1 to 9 bar (14.5 to 130.5 psi) and has NBR seals for operation in temperatures from 0 to 60°C (32 to 140 °F) without freezing. This product is available for purchase in the United Kingdom.
