Safety screen filters are critical components in hydraulic, fuel, lubrication, or pneumatic systems within the aerospace and defense industries. While the filters maintain fluid cleanliness, sudden failures can occur due to improper contaminants or debris that remain in the system during production or are generated during operation. We offer a wide variety of standard designs across various sizes, materials, mounting methods, filtration ratings, and even technologies. In fact, our Hi-Bar-Screen is the first invention of laser-drilled screen technology that provides the industry with a robust, cost-effective design capable of withstanding burst pressures of up to 7500 psid. More than 50% of the filters we manufacture are custom-made, far exceeding our standard product line. This includes, for example, drill hole sizes ranging from 25 microns to 1500 microns, a diverse range of materials, higher burst pressures, or unique envelopes optimized for lower resistance, custom mounting, or integrated bypass mechanisms.

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.

Aircraft are designed with redundancy in mind. In cases where redundancy is not practical, such as with landing gear and brakes, a 3-port shuttle valve can provide backup control for a single system. The Lee Shuttle Valve is designed to be integrated into landing gear and brake systems as a method to switch between the main control line and the emergency control line as needed. The Lee Shuttle Valve is available in various sizes/configurations to meet the needs of any application. Since shuttle valves typically operate during emergencies, reliability over the aircraft's lifespan is crucial. Therefore, it is designed to last throughout the aircraft's 30-year lifespan by utilizing a robust stainless steel construction. Each component is also designed to be compact, lightweight, and easy to install. The Lee Shuttle Valve incorporates a unique nose seal design that eliminates bypass leakage and the need for additional O-rings.

The vulnerability of mesh filters under specific environmental conditions has been pointed out. Contaminant accumulation + flammable fluid = localized high-temperature state >> damage. Depending on usage, wire mesh can create situations where localized high temperatures occur. Filters manufactured with laser drilling have smooth surfaces and do not accumulate contaminants locally like mesh nets, and they do not break even if all holes are clogged. The failure of a filter, which is supposed to protect the system, can lead to significant damage to the system. In the aviation industry, this type of filter is adopted to ensure absolute reliability. Its technological value is believed to contribute to the development of combustion systems using hydrogen and ammonia in the future.
