Rotary Control ValvesThe rotary control valve is a directional control valve actuated in a rotary motion. With high pressure and zero-leak performance, the valve is designed and manufactured to meet your requirements for both topside and subsea applications.

Our rotary control valves are regularly integrated into:

» Drilling control systems

» Blow out preventers (BOPs)

» Subsea X-mas trees

» Hydraulic based industrial applications

» Subsea intervention systems

» Chemical processing plants

» Remotely operated vehicle (ROV) systems

Designed based on the shear-type-seal principle, our rotary control valves deliver advantages when compared to conventional alternatives, including negligible internal leakage and superior resistance to wear. Our valves are designed to meet—and often exceed—a service life of at least 30 years. With a design that has evolved over 50 years, the valves are widely used in both topside and subsea applications. The valves feature metal-to-metal sealing with internal components that can be configured with materials to meet operational needs.

Flow CoefficientNote: Given Cv value is for valve only.

Flow coefficient for the control valves, Cv value, is based on tests according to IEC Publication 534 – Part 1, 2.1 and 2.3. Measurements are conducted on pure water at 5°C to 38°C with turbulent flow conditions through the valve. For conditions other than these, flow can be obtained using the following formulae, rewritten for [l/min] and [bar] as input values plus theoretical compensation of viscosity:

Test according to IEC Publication 534 give the Cv value with a precision of ±5 %.
