Shuttle Valves
Pneumatic shuttle valves have three ports and allow compressed air to flow from one of two sources, directing it through to a common port. Once the pressure from one source overcomes internal pressure, the shuttle valve shifts and closes the other source port, allowing media to flow outward.
The dual source control function and limited moving components make shuttle valves effective for pneumatic systems with repetitive operations. They’re typically used for function controls with multiple locations and various pneumatic media and pressure regulation.
Our Products
Quick Exhaust Valves
Humphrey Super Quick Exhaust Valves are versatile and available in six models, from 1/8 to 3/4 PIPE size. They’re commonly used as shuttle valves in industrial applications and provide excellent flow capacity. Exhausting air from the common port vents media to the third port.
TAC Miniature Quick Exhaust Valves
Humphrey’s TAC total air control valves and accessories include two miniature shuttle valve models with 10-32 UNF and 1/8 NPSF ports. The miniature design is capable of delivering precise media flow to a common outlet.
Benefits of Using a Shuttle Valve
Shuttle valves are efficient and don’t require operator input to function. They’re also compatible with a variety of gas media, including air and inert gases.
Other benefits include:
Automated selection: These valves automatically select the high-pressure source, eliminating the need for an external operator and potential human error.
Compact design: The small and lightweight construction is piped inline without the need for mounting.
Reliability: The simple design has few parts, reducing the opportunity for failure. You can expect millions of cycles from a single valve.

FAQs
Shuttle valves used in pneumatic systems typically don’t require lubrication. However, lubrication may be necessary to control valves and air cylinders.
Generally, yes, but it depends on the valve and seal material type and media compatibility.
