In aircraft fuel, hydraulic, and pneumatic systems, it is necessary to accurately control the flow and pressure conditions. Lee offers a variety of valves with additional features for applications where basic flow restriction devices are insufficient. In addition to their primary use in aerospace, they are also used in numerous defense applications such as missiles, tanks, submarines, and frigates. Due to the significant differences in functionality when combined, flow measurement valves are an interesting category. Restrictor Check: It integrates a check valve and an orifice in series into one component. It allows a metered flow in one direction while preventing flow in the opposite direction. Directional Flow Controls: It has the functionality of a check valve and an orifice in parallel, allowing free flow in one direction and restricted flow through the orifice in the opposite direction. It provides different metered flow rates in each direction. Flosert: Compact and lightweight, it incorporates both fixed and variable metering orifices to provide a constant flow rate across a wide differential pressure range. By combining the functions of two components into one package, it can offer superior performance compared to the sum of the individual components.
