Counterbalance Valve Protection: 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.
Industrial Series Overview: The WL30 Series hydraulic rotary actuator is designed for harsh environments. It is a heavy-duty helical rotary device with torque output from 1900Nm to 24000Nm at 21Mpa. The series features rear flange and front flange mounting types, with rotations of 180 degrees and 360 degrees.
The load is mounted to the shaft flange and is supported at only one end of the shaft. Cantilever mounting is not recommended for aerial work platforms or other critical and safety-related applications.
The load is supported at both ends of the shaft, providing superior stability for high-moment applications.
Torque Versus Hydraulic Pressure and Loads: 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%.
