The counterbalance valve protects rotation in the event of a hydraulic line failure and protects the actuator against excessive torque loading. The counterbalance valve is optional on-demand. SUN brands or other top brands are available for different requests.
The WL20 Series hydraulic rotary actuators offer a cost-effective solution for wide applications. Five standard sizes with torque output from 500Nm up to 4200Nm at 21Mpa. It provides 180 degree rotation with foot mounting type. Typical usage includes aerial platforms, cranes, spider lifts, and material handling.
Cantilever Mount: The load is mounted to the shaft flange and is supported at only one end of the shaft. Not recommended for aerial work platforms or safety-critical applications.
Straddle Mount: The load is supported at both ends of the shaft.
The driving torque and holding torque are approximately linear with hydraulic pressure. As moment loads increase, drive torque may be reduced by up to 15%.
