Dual Metering Flow Control Valves
The Lee Company’s dual metering flow control valves are two-way restrictors that allow a designer to specify a different metered flow rate in each direction. These valves are ideal for high-pressure hydraulic applications with system pressures up to 5000 psi. They feature all stainless steel construction for durability and long life and are available in 0.187 and 0.281 inch diameter models. Each Lee Dual Metering Flow Control is 100% tested in both flow directions to ensure reliable, consistent performance.
Because each direction can be specified differently, our dual metering flow controls can achieve a nearly infinite combination of metered flow rates. As such, all of these components are supplied as custom items to meet the specific needs of an application.

Lee Bender Jet Multi-Orifice Restrictors
As the name suggests, Lee Bender Jets use multiple offset orifices in series. Each additional restriction causes an increased reduction in flow. This produces an effect that results in an increased minimum passage size for a given Lohm rate. The valve’s components are protected with two integral safety screens for bi-directional flow and are available calibrated to a ±5% tolerance in the range of 125 to 9500 Lohms.
Bypass Valves
Known for their durability, longevity, and small size, Lee bypass valves are designed to shunt flow across an actuator piston when the system pressure is either shut off or lost. They are normally open, with a hydraulically actuated pilot-to-close feature. These stainless steel valves are available in a 0.375 inch diameter insert for system pressures up to 4000 psi, have a maximum restriction of 70 Lohms when fully open, and weigh only 16 grams each. Similar to Lee shuttle valves, Lee bypass valves include a polyimide compression seal to ensure there is no external leakage across the three-port design when properly installed.
High Flow Check Valves
Our line-up of poppet-style check valves offers extremely high flow capacity for their size in comparison to ball-style valves and includes our Lo-Lohm Cheks, Hi-Q Cheks, and High Pressure Cheks. The High Pressure Chek starts at a micro-miniature 0.125-inch diameter, yet still withstands up to 8000 psi. Meanwhile, the Hi-Q Chek offers the greatest feasible flow capacity for valves of this size. Available in sizes up to 1 inch in diameter in a cartridge configuration, the Hi-Q Chek valve can flow over 57 GPM with only a 100 psid pressure drop. Finally, the 0.250-inch Lo-Lohm Chek offers 3.5 times more flow than an axial flow ball-style check valve of the same diameter.
