170 Spring Retained Etched Safety Screen
Lee Etched Safety Screens feature a seamless, one-piece, 304L CRES screen element formed with pleats to greatly increase the dirt carrying capacity of the screen. The result is a robust screen design with an optimum amount of protection in a small package. Lee etched safety screens are offered with several standard hole sizes including 75, 100, 150, 200, 250, 380, and 500 microns. Lee Spring Retained Safety Screens include a flange mount etched safety screen and a retention spring. This combination allows for an inexpensive mounting technique suitable for unidirectional flow. The spring O.D. is slightly larger than the I.D. of the mounting hole and a special tool is used to twist the spring into the hole. Once the tool is removed, the spring holds the screen in place.

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.
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.
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.
