Pisco JKC4-01B1p8IN 4mm x OUT R1/8" Straight 1.8mm Orifice Meter-In Check Valve

The Pisco straight orifice check valve effectively regulates airflow in one direction. Its 1.8 mm orifice restricts flow in one direction while allowing free flow in the opposite. With a cracking pressure of 0.5 bar, it's designed to obstruct the flow going from the male threaded port to the push-in fitting (meter-in configuration). The opposite is true for the meter-out configuration. Featuring a 4 mm push-in fitting on one end and an R 1/8 inch male threaded port on the other, it provides easy tubing connections. The push-in fitting employs stainless steel claws to secure the tube. Operating within a pressure range of 1 to 9 bar (14.5 to 130.5 psi) and a temperature range of 0 to 60°C (32 to 140 °F), it's protected by NBR seals. Available in the United Kingdom, this valve is ideal for applications requiring one-directional fixed airflow control.
