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 WL30 Series hydraulic rotary actuator is a heavy-duty device designed for harsh environments. With torque output from 1900Nm to 24000Nm at 21Mpa, this foot-mounting helical actuator features 180-degree and 360-degree rotation options. Ideal for Agriculture, Construction, Energy, Marine, Material Handling, Military, Mining, and Truck/Trailer industries.
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%.
