The All-Hydraulic ARV (ARV-H) can accommodate a wide range of tension and water depth scenarios — all with no required feedback for the position of the tensioner rod. That’s because the engineers behind the Olmsted valves provided by Oilgear developed a proprietary means of achieving the majority of the features of the electro-hydraulic ARV without electronic controls.

The Olmsted Anti-Recoil Valve (ARV) is the global standard for control of offshore riser tensioning systems. And it leads for safety during emergency disconnect sequences (EDS). That’s because they’re part of the Olmsted legacy. Over the decades, Oilgear's Olmsted group has pioneered the art of valving for motion compensation applications.

The modern Flow Shut-Off (FSV) Valve is a complex, precision instrument that can have numerous control and safety functions. As an Olmsted product, it has a legacy of innovation for motion compensation applications. They pioneered the field. Now, FSV has that history with the modern support of Oilgear.
