Walvoil VOSL/CC Single Counterbalance Valve – 3/4" BSP, 120 L/min, 350 Bar, Pilot Ratio 1:7
Walvoil VOSL/SC/CC 34/TR.S.p7.PG single counterbalance valve is a high-performance solution designed for load control, stability, and safe hydraulic operation in demanding mobile and industrial systems. It is used to control overrunning loads, prevent uncontrolled movement, and ensure smooth and controlled actuator operation.
Built with a robust design and available in steel construction for high pressure applications, this valve is suitable for heavy-duty hydraulic environments. With a pilot ratio of 1:7, it provides precise and responsive load control, helping to improve safety and system efficiency in load-holding circuits.
With a nominal flow rate of 120 l/min and a maximum operating pressure of 350 bar (steel body), the VOSL/SC/CC 34 is ideal for high-flow, high-pressure systems. Its design ensures reliable performance while maintaining low internal leakage and consistent operation across a wide range of applications.
