Adjustable Needle Bidirectional Valve
Compact cartridge-style bidirectional throttle valve designed for manifold or valve-block integration. It provides stepless flow adjustment in both directions — useful for fine speed control of small actuators and pilot circuits where a direct-mounted valve body is not practical.
Available with either knob or screw adjustment, and a locking screw to secure the selected setting. The cartridge cavity code is DO-590.001.51.2S.
