Our proprietary floating seal is at the heart of many solenoid valve designs in our catalog. In principle, the seal disc is free to float between two optically flat seats, creating a bi-directional gate-style valve that prevents particles from accumulating on the sealing surface of the seats. Every time the valve is actuated, the seal disc wipes across the seat, pushing any particulate out of the way to ensure a tight seal. We also offer a broad selection of traditional poppet-style valves.
Floating seal and poppet valves are found in many military and commercial fixed wing and rotorcraft applications. Typical applications include engine starting, running, and deicing control. They are also used for firewall shutoff and fuel manifold purging. These valves are especially designed for dependable operation under high vibration and temperature extremes typical during flight. Designs are available for pneumatic, hydraulic, and fuel control systems.
