Extreme Environment Check Valves

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 Boss Mount Etched Safety Screens incorporate a threaded configuration and are available in six sizes ranging from 0.3125″ to 0.7500″ in addition to a metric 10mm thread.

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 miniature piloting solenoid valves are the most compact powered components we offer, available in a configuration just 0.875 of an inch in diameter and weighing less than 0.14 lbs. Their threaded bodies are easy to install and maintain and are available for system pressures up to 5000 psi. Meanwhile, the efficient coil design requires power levels as low as 7.8 Watts at 28 Vdc. Many options are available, including a single or dual coil configuration, 2-way or 3-way porting, a normally open or normally closed position, and a customizable electrical interface.
