Counterbalance Valve Protection: The counterbalance valve protects rotation in the event of a hydraulic line failure and protects the actuator against excessive torque loading. Hydraulic Schematic of Optional Counterbalance Valve: The counterbalance valve is optional on-demand. Top brands are available for different requests.
Mobile hydraulic rotary actuators offer simple and cost-effective solutions to move, support and position rotating loads in countless applications. The actuators are designed to replace multiple components and function as a rotating device, mounting bracket and bearing, all-in-one. They feature tremendous torque output and exceptional load bearing capability in compact dimensions.
The WL30 Series is a heavy duty helical hydraulic rotary actuator that is suitable for harsh environments. Designed for applications that require high bearing capacity, the WL30 Series features foot or flange output with 180° or 360° rotation. 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).
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.
