High-performance motorsport vehicles often need to switch between different control lines to guarantee both speed and safety. For this reason, Lee shuttle valves are often used in critical vehicle systems such as the emergency clutch actuation.
Lee shuttle valves are available in various sizes and configurations to meet the needs of any application. Because shuttle valves commonly operate during emergencies, reliability is critical. Therefore, Lee shuttle valves feature robust stainless-steel construction that allows them to operate in the challenging environments associated with motorsports.
Each part is also designed to be compact, lightweight, and simple to install. Lee shuttle valves are engineered with a unique nose seal design that eliminates bypass leakage and any need for additional O-rings. Choose from spring-biased shuttle valves, spring-detented shuttle valves, selective shuttle valves, inverse shuttle valves, or zero leak shuttle valves – you’re almost sure to find a configuration that works for you.
Over half of the products we offer are designed for the unique needs of a specific application. Shuttle valves can be designed in custom envelopes and configurations with unique shuttling pressures, flow rates, leakage specifications, materials, and more. Contact your local Lee sales engineer to discuss your specific needs.
This valve configuration is typically used to select between a primary pressure source and an emergency backup that’s biased in the normally-closed position. Its non-interflow design means that its three ports are never open simultaneously. These valves can also be used to extend a large unequal area actuator, where reduced actuation force may be permissible in one direction. They are available in sizes from 0.187 to 0.500 of an inch.
Detented shuttle valves are designed with a mechanically latched poppet that can close off one of the two inlet ports. This design is typically used in applications where bi-directional flow may be required between either of the inlet ports and the outlet port. Detented shuttle valves are also of the “non-interflow” type, which is a common requirement in high-performance motorsport applications. This valve comes in 0.187, 0.281, 0.375, and 0.500 inch diameters as a standard product. Zero leak versions are also available.
This is our standard non-biased loose-ball design. Available in 0.187, 0.281, 0.375, and 0.500 inch diameters, this is the most economical configuration we offer. The maximum shuttling pressure is just 1 psid. The valves are rated for leakage of fewer than 1 mL per minute.
Inverse shuttle valves may be used to replace two check valves in providing an anti-cavitation and anti-pressure intensification function in hydrostatic actuation systems. Unique among shuttle valves, these components flow liquid from the lower pressure port while the higher inlet pressure is blocked. They’re available in 0.250 and 0.500 inch diameters.
Zero leak versions of the spring-detented and spring-biased shuttle valves are available with polymeric valve seats to eliminate leakage. Detented shuttle valves are available with polymeric seats on both the normal and emergency ports. These polymeric seats provide a tighter seal in applications where eliminating any leakage is critical. This is particularly critical in applications using a gas-operated backup emergency system. Zero leak valves are available in 0.281, 0.375, and 0.500 inch diameters. Contact your local Lee sales engineer for custom versions of a spring-biased shuttle valve with a polymeric valve seat.
