Valves Option
Hydraulic Schematic of Optional Counterbalance Valve
The counterbalance valve is optional on-demand. SUN brands or other top brands are available for different requests.
A counterbalance valve in a helical hydraulic rotary actuator is crucial to enhance safety and control in hydraulic systems. It performs several important functions, including preventing uncontrolled motion of the actuator, maintaining load stability, and managing pressure within the system.
