Shuttle Valves for Oil and Gas

Back-Up Critical Hydraulic Systems with Lee Shuttle Valves

Oil and gas equipment need some form of redundancy to mitigate potential failures within subsystems. Here, a three-port shuttle valve can be used to provide backup control of a single system. Lee shuttle valves are designed into downhole and subsea equipment to switch between primary and emergency pressure sources when needed as well as to serve selector functions.

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 over the life of the oil well is critical. Therefore, Lee shuttle valves are designed to last for the entire life cycle of an oil tool regardless of function downhole and subsea..

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 sure to find a configuration that works for you.

In addition to our wide range of catalog products, over 50% of components manufactured by The Lee Company are unique products designed to meet the requirements of a specific application. So whether it is flow rate, leakage, shuttling pressure, envelope, or material, contact a local Lee Sales Engineer for help solving your latest fluid control problem engineer to engineer.

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. Our spring-biased shuttle valves are available in sizes from 0.187 to 0.500 of an inch.

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. 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.

Selective Shuttle Valves

This is our standard non-biased loose-ball design. Available in 0.187, 0.281, 0.375, and 0.500 inch diameters, these are the most economical configuration. The maximum shuttling pressure is just 1 psid. The valves are rated for leakage of fewer than 1 mL per minute.

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. They’re available in 0.250 and 0.500 inch diameters.

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. 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.
