This pneumatic flow control valve allows precise adjustment of airflow in one direction. Combining a needle valve for flow rate regulation and an orifice check valve for unidirectional flow, it operates from 7.25 to 72.5 psi and features NBR seals for temperatures between 32 and 140 °F. Its rotatable needle adjusts the orifice size, controlling flow rate, while a locknut secures the settings. The 1/8-inch push-in fitting on one side simplifies tubing connections, while the M3x0.5 male threaded port provides secure connections on the other.
