Counterbalance Valves (Overcenter Valves)

Compare Valve Series by Pressure and Flow Range

Each counterbalance valve series on this page offers different performance specs to meet specific system requirements. Options like the 1CEV30 and 1CEV90 are rated up to 4000 PSI with flow capacities up to 23 GPM, while higher-pressure models such as the 1SE30 and 1SE90 handle up to 5000 PSI. If your application requires lower flow, the 1CE30 Series provides up to 8 GPM with multiple pilot ratio options.

Whether you need a compact solution for confined installations or higher flow capacity for demanding systems, HSC’s product selection allows you to sort by flow, pressure, and adjustment type. Explore our full range of hydraulic valves and accessories for system integration.

Applications for Counterbalance and Overcenter Valves

Counterbalance valves are essential for systems that support a suspended or moving load. Common applications include boom lifts, scissor lifts, hydraulic winches, industrial hoists, and mobile machinery with vertical actuators. These valves maintain back pressure to prevent load drift and provide smooth, controlled motion when lowering or lifting. Pair with compatible hydraulic cylinders and accessories to complete your system.

HSC’s overcenter valve selection supports both standard and high-pressure systems in mobile and industrial environments. Many models include screw adjustment for fine-tuning valve response to match specific hydraulic system needs. See the industries we serve for more examples of where these valves are used.

Valve Adjustability and Pilot Ratio Options

Several valve series in this collection, including the 1CE30, 1CEB90, and 1SE90, are built with external screw and locknut adjustment. This feature allows technicians to modify valve settings in the field based on system pressure or load behavior. Available pilot ratios—such as 2.5:1, 4:1, and 5:1—provide options for tuning valve response to match different actuator types and lifting scenarios. 

Choosing the right pilot ratio helps ensure efficient performance without overloading the system. If you need help selecting the right valve for your system, contact us for technical support.
