With the history and innovation of Olmsted technology, motion compensation valves from Oilgear are renowned across the world for their control and safety protection. Oilgear motion compensation valves specialize in controlling compensator and tensioner systems. And our drill string compensator valves and riser anti-recoil control systems are on nearly every existing drill ship.
The Olmsted product line from Oilgear contains some of the fastest-acting, large relief valves in the world. These complex, proprietary electro-hydraulic products not only provide control of a rig’s passive heave compensation systems, but also provide critical safety protection for personnel and equipment.
All-Hydraulic ARV | Riser Anti-Recoil Control, Without a Control System
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.
Crane | Specialized Safety and Control Valves for Offshore Cranes
Like other products in Oilgear’s Olmsted line, crane valves have a history of innovative engineering and proprietary technology. Oilgear crane valves need features that can handle specific challenges like loss of load protection, command open and command close — all with specialized safety and control valving.
DSC | Leading Drill String Compensator Valves
Oilgear’s Drill String Compensator (DSC) valve is a complex, precision instrument with numerous control and safety functions. That’s because it’s backed with decades of innovative engineering. Olmsted, now part of Oilgear’s legacy, pioneered the art of valving for motion compensation applications.
Electro-Hydraulic ARV | The Global Standard in Riser Disconnect Recoil Control
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.
FSV, Gas | Laboratory-Tested Velocity Fuses
By way of the Olmsted product line, Oilgear offers flow shutoff valves for gas media. These velocity fuses are factory verified to guarantee their shutoff flow rate in the field. They are typically utilized on offshore compensation systems to protect against hose bursts and hose ruptures.
FSV, Liquid | The Global Standard in High-Flow, High-Pressure Velocity Fuses
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.
PCGFSV | From the Inventors of the Pressure-Compensated Gas Safety Valve
The highest level of safety and protection during a broken hose event. All available from Oilgear by way of its Olmsted product line and the Pressure Compensated Gas Flow Shutoff Valve (PCGFSV). In fact, Oilgear is the only company in the world to offer it. And we’ve been producing velocity fuse, flow shutoff valves for more than 40 years.
