Performance

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%.

Valves Option

WL10 Series 200Nm Helical Hydraulic Rotary Actuator (4)

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.

Mounting Type

Cantilever Mount

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.

Straddle Mount

The load is supported at both ends of the shaft.
