    Flow-Adjustment Inline Hydraulic Valves

    Turn the dial to gradually adjust the amount of flow. Five colored rings on the valve stem represent different flow rates. Adjust the dial until you see the color of the flow rate you need.
    One Direction with Unrestricted Reverse—NPTF Female
    Image of Product. Front orientation. Flow-Regulating Valves. Flow-Adjustment Inline Hydraulic Valves .
    One-direction-with-unrestricted-reverse valves regulate flow in one direction while allowing oil to flow freely in the opposite direction.
    NPTF (Dryseal) threads are compatible with NPT threads.
    Brass Body—Brass valves have better corrosion resistance than steel valves.
