Rotary Actuators – HyRAV Rotary Actuator

The HyRAV model is Eckart’s hydraulic quarter-turn valve actuator, built for automating industrial valves in demanding environments. The series covers 12 drive sizes with torque up to 250,000 Nm at 210 bar. Rotation is offered in 0–90°, 120°, or 180°+, with positioning accuracy under 0.5° of full scale. Both double-acting and spring-return (fail-safe) versions are available, with operating times from 0.5 to 200 seconds and fail-safe response as fast as 0.1 seconds.

The valve actuator functions according to the principle of helical gears. The compact and concentric design of the valve has proven to be excellent in practice and provides the customer with space savings as well as reliability. Moreover, the HyRAV series can be applied in the most severe conditions, i.e. from high vibrations to severe environmental locations, and further, provides a powerful, safe  solution for automation of valves. Additionally, the series is easily adapted to all types of valves, what is a result of the generous design of the hollow shaft and adaptable flange types.
