The Lee Company makes three different kinds of Flow Controls:
Restrictor Check Valves
Lee Restrictor Cheks® are miniature 0.187" valves that provide metered flow in one direction and no flow in the other direction. They are functionally equivalent to a check valve in series with a flow restrictor. Learn more.
Directional Flow Controls
Lee Directional Flow Control valves provide metered flow in one direction, and free flow in the opposite direction. Functionally equivalent to a check valve in parallel with a flow restrictor, they are available in four diameters (0.187" - 0.500") with models available for 3,000, 5,000 and 8,000 psi systems.

Lee Flosert® flow regulators are pressure compensated flow control valves that provide a constant flow over a wide range of differential pressures. They are available in two diameters (0.281" and 0.500") and a range of flow rates for 3,000 and 5,000 psi systems. A NACE compliant model is also available for pressures up to 8,000 psi. Learn more.
