Rotary Actuators – HyRAV Rotary Actuator
HyRAV® – more powerful, compact, safer and tailored perfectly to your demands The hydraulic valve actuators HyRAV of Eckart, form a full series of double-acting actuators or spring return actuators 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.
