Ø .281" Directional Flow Control - High Pressure


    The Lee Company's new 281 High Pressure Directional Flow Control is the latest addition to Lee's line of miniature directional flow control valves. These valves provide restricted flow in one direction and free flow in the other direction. This new valve is ideal for high pressure hydraulic applications with system pressures up to 5000 psi, and incorporates high strength safety screens for both flow directions. Nominal weight is just 6 grams.

    Available in forward and reverse free flow configurations, the new Lee 281 High Pressure Directional Flow Control is constructed entirely of stainless steel for durability and long life. Metered Lohm rates are available from 1000 to 10,000 Lohms. Maximum free flow restrictions are as low as 175 Lohms. Each directional flow control valve is 100% tested and inspected to ensure reliable, consistent performance.
    • Designed for system pressures up to 5000 psi
