ABCO Subsea’s Andy Boyd patented the first multi-input shuttle valves more than 30 years ago. Today, ABCO Subsea’s shuttle valves are installed on over 20 percent of the world’s deepwater drilling fleet, making the company one of the world’s largest providers of BOP shuttle valves to the offshore industry. ABCO Subsea’s hydraulic shuttle valves have a modular design with port orientations that can be rotated in 90° increments, allowing our customers flexibility in unitizing their valves on a BOP stack. Our valve bodies are manufactured in stainless steel and internal working spools and plugs are manufactured in naval bronze.

Web_new-shuttle-valvesOur standard valves are designed and tested to a 6,000 psi rated working pressure, but higher ratings are available for custom applications. Our standard valves are made with Code 62 modified flanges, but other options are available, including JIC, NPT, Autoclave, and SAE UN O-Ring. Valve sizes range from 1/4″ to 1.5″.

ABCO Subsea offers training and certification courses on the maintenance and assembly of its BOP hydraulic valves.
