Hydraulic Schematic of Optional Counterbalance Valve: The counterbalance valve is optional on-demand. SUN brands or other top brands are available for different requests.
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%.
