The counterbalance valve protects rotation in the event of a hydraulic line failure and protect the actuator against excessive torque loading. Hydraulic Schematic of Optional Counterbalance Valve. The counterbalance valve is optional on-demand. SUN brands or other top brands are available for different requests.

WL30 Series hydraulic rotary actuator is designed for harsh environment. It is heavy duty helical rotary device with torque output from 1900Nm to 24000Nm at 21Mpa. The WL30 Series features mounting type of rear flange and front flange mounting, with rotation of 180 degree and 360 degree. It is wide used for fields of agriculture, Construction, Energy, Marine, Material Handling, Military, Mining, Truck/Trailer, etc.
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. See specification pages for valve location. The pilot ratio is 3:1. The valves are set to relieve at 3300 psi ± 300 psi (228 bar ± 21 bar).
