Kofloc Model 2412D Large Capacity Precision Needle Valve: This large capacity needle valve exhibits high performance in precision control of comparatively large flow. The needle valve is a larger version of our precision needle valve (Model 2412) that has time-tested reliability and is suitable for stable control in a comparatively large flow range of 50–300 l/min (0.1 MPa).
A needle valve is the typical flow control valve that controls the flow rate based on the change of resistance of the flow channel using an acicular or rod-shaped needle to adjust the opening of the flow channel that functions as a small orifice. KOFLOC offers simple-type, precision-type and various other needle valves, and also manufactures flow controllers having a combination of a needle valve and diaphragm as well as proportional solenoid valves that electrically control the flow rate.
