The GNV-4K is a direct mount needle valve with 1/4" NPT ports, designed for bidirectional flow control in pneumatic systems using air, water, or oil. It features a knurled knob adjustment, an electroless nickel-plated brass body and needle, anodized aluminum housing, and standard nitrile seals. The valve supports a maximum input pressure of 300 psig and provides an air flow rate of 45 scfm at 100 psig. It includes a 360° rotating input port and is compatible with push-quick fittings. The physical dimensions are 0.890 inches in length and 0.575 inches in pipe thread size, with a square body measurement of 0.750 inches. Mounting is direct or in-line, with pre-applied sealant included.
Adjustable control needle valves restrict flow in both directions. There are eight models offered by Clippard with various ports and needle configurations to provide coarse or fine flow adjustment. The diagram of needle shapes and the part show the difference between these models.
