Super-Vee™ Flow Control and Needle Valves by Fabco-Air are designed for air or hydraulic service up to 150 psi and feature no tapered needles. All models feature Delrin® control bushings, and are repairable. A unique large "V" shaped adjustable orifice is more forgiving in real world applications, and allows for much larger contaminates to flow through freely and thus not be caught and obstruct flow rate, when compared to traditional tapered needle and orifice designs.
