AS9100/ISO 9001

Lourdes continues to demonstrate an unrivaled commitment to quality by achieving and maintaining, at our Hauppauge facility, registration as an AS9100 and ISO 9001 certified company since 2005, most recently by NQA.

Wireless Fittings

Patented self-locking fluid fittings with redundant design to prevent joint loosening

Lourdes Wireless Fittings feature a unique patented self-locking design that incorporates a redundant locking scheme completely independent of the threads. This creates substantial frictional forces and prevailing torque, effectively preventing self-loosening of fluid fitting joints even under extreme vibration, thermal cycling, and dynamic loads. Ideal for mission-critical aerospace, defense, and industrial fluid systems requiring maximum reliability and safety.

Solenoid Valves

Fast-acting, custom solenoid valves for fuel, pneumatic, and hydraulic applications

Lourdes solenoid valves are engineered for fast, positive motion and exceptional reliability in fuel, pneumatic, and hydraulic systems. Custom-designed and manufactured to the highest safety and quality standards, they perform reliably across widely varying electrical power conditions—from abundant to severely limited. Built to operate in virtually any environment on land, in the air, or at sea, including extreme temperatures, pressures, and vibration profiles.

Butterfly Valves

Versatile butterfly valves with low pressure drop for pneumatic and fuel systems

Lourdes butterfly valves are specifically designed for pneumatic and fuel applications, available in a wide range of sizes and activation methods (gas, air, or fuel flow). They deliver consistently low pressure drop across diverse environmental conditions and can operate effectively in any attitude. Deployed successfully in ground support equipment, shipboard systems, and aircraft platforms, these valves are offered in Inconel, titanium, stainless steel, or aluminum per customer specifications and can handle high temperatures and broad pressure ranges.

Cartridge Valves

High-reliability, zero-leakage cartridge valves for military and commercial use

Lourdes custom cartridge valves are precision-engineered for both military and commercial fuel, pneumatic, and hydraulic systems. They offer zero leakage, high operating pressures, and a broad range of flow rates while demonstrating outstanding reliability in the most demanding environments—on land, in the air, and at sea. Constructed from aluminum, stainless steel, or exotic materials to meet exact application requirements, these valves provide proven performance where failure is not an option.

Shuttle Valves

Precision shuttle valves designed for rugged hydraulic, pneumatic, and fuel duty

Lourdes shuttle valves are precision-manufactured for hydraulic, pneumatic, and fuel applications in both military and commercial platforms. These rugged components deliver high reliability under adverse environmental conditions across land, sea, and air systems. They operate over a wide pressure range with minimal pressure drop and extremely low internal and external leakage. Available in stainless steel or aluminum, they are tailored to meet specific customer design parameters and performance demands.

Dehydrators

Reliable, low-maintenance dehydrators for drying air in sensitive cable assemblies

Lourdes dehydrators effectively remove moisture from ambient air in microwave, antenna, cable, and fiber optic cable assemblies. Engineered for high reliability and very low maintenance, they are easily serviced on-site without specialized tools. Units can be supplied as integrated component parts for larger systems or as fully self-contained, free-standing devices. Fully customizable to match exact configuration, size, and performance requirements of any application.

Swivel Assemblies

Low-torque swivel assemblies for hydraulic and pneumatic systems with radial motion

Lourdes swivel assemblies are designed to accommodate radial movement in hydraulic and pneumatic systems while maintaining low torque. Common applications include aircraft landing gear, flight control systems, ground/sea-based antenna arrays, gun turrets, and missile launchers. Built from standard metals or exotic materials such as titanium, they withstand extreme environmental conditions and dynamic stresses. Hydraulic versions provide full flow, minimal pressure drop, high operating pressures, very high proof pressure, and exceptional burst strength.

Drain Valves

Lightweight, zero-leakage drain valves for aircraft fuel and water drainage systems

Lourdes drain valves are engineered for the critical task of removing water and fuel from aircraft fuel systems. Constructed from lightweight stainless steel, aluminum, or composite non-conductive materials, they operate across a wide range of flow rates with zero leakage. Valves made from non-conductive materials offer the added benefit of being lightning-proof, enhancing safety in aerospace applications where electrical discharge risks must be minimized.

Pressure Switches

Highly accurate and repeatable pressure switches for critical aerospace applications

Lourdes pressure switches provide industry-leading reliability, accuracy, and repeatability across very low to very high activation pressures. Widely used in demanding applications including torpedoes, missiles, hovercraft, and other platforms in fuel, hydraulic, and pneumatic systems. Manufactured from stainless steel, aluminum, or exotic metals as required, these switches deliver consistent performance in mission-critical environments where precision and durability are essential.

Check & Relief Valves

Fully custom check and relief valves engineered to meet the toughest specifications

Lourdes check and relief valves are completely custom-configured to satisfy even the most challenging design criteria in fuel, pneumatic, and hydraulic systems. Every valve is tailored to exact performance, pressure, flow, material, and environmental requirements. With proven reliability in military and commercial applications, these valves deliver dependable operation under extreme conditions where precise pressure control and backflow prevention are critical to system integrity.

Harness Assemblies

Precision-engineered harness assemblies for reliable electrical and fluid integration

Lourdes harness assemblies are meticulously designed and manufactured for specialized electrical and fluid system integration in aerospace, defense, and industrial applications. Built to exact customer specifications, they ensure dependable performance, durability, and compatibility in harsh operating environments. Whether for power distribution, signal transmission, or combined electro-fluid systems, these harnesses provide long-term reliability and ease of installation in mission-critical platforms.
