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 designed for harsh and tough conditions. It is a heavy-duty helical rotary device with torque output from 1900Nm to 24000Nm at 21Mpa. The WL30 Series with foot mounting helical actuator has 180-degree rotation and 360-degree rotation. It is widely used for fields of agriculture equipment, construction machines, energy, marine, lifting, military, mining, truck/trailer, etc.



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%.
Standard Valve for L30-17 and L30-25 180 Degree Models: Manufactured from aluminum, the valve blocks are bolted to a flat mounting pad on the actuator housing. Three bolts secure the valve block to the actuator. The pilot ratio is 3:1. The valves are set to relieve at 3300 psi ± 300 psi (228 bar ± 21 bar).
