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 is available on-demand. SUN brands or other top brands are available for different requests.
WL40 Series Helical Rotary Actuator is ideal for applications that requests torque generation and high cycle rate. It features output shaft and 220 degrees of rotation. The torque output from 2800 Nm up to 6700Nm.
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%.
