Back-Up Critical Hydraulic Systems with Lee Shuttle Valves

Shuttle valves serve many purposes in hydraulics. Sometimes, a three-port shuttle valve is used to switch between primary and emergency control lines in critical systems. Other times they’re used to provide sensitive steering controls in applications such as off-highway vehicles. No matter what you use a shuttle valve for, however, the best shuttle valve is one that comes from The Lee Company.

Lee shuttle valves are available in various sizes and configurations to meet the needs of any application. Because shuttle valves may operate during emergencies, they must remain reliable throughout the life of the product. Therefore, Lee shuttle valves are designed to last for the entire product lifecycle.

Each part is also designed to be compact, lightweight, and simple to install. Lee shuttle valves incorporate 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.

Spring-Biased Shuttle Valves

This valve configuration is typically used to select between the main hydraulic system and the emergency backup that’s biased in the normally closed port. 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.

Detented Shuttle Valves

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 brake systems 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. Zero leak versions are also available.

Selective Shuttle Valves

This is our standard non-biased loose-ball design. It is the most economical configuration. The maximum shuttling pressure is just 1 psid. The valves are rated for low leakage.

Inverse Shuttle Valves

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.

Zero Leak Shuttle Valves

Zero leak versions of the 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. Contact your local Lee Sales Engineer for custom versions of a spring-biased shuttle valve with a polymeric valve seat.
