Counter balance valves from Power Team SA can be used for both single- and double-acting cylinders. They provide positive holding and controlled ‘chatter-free’ lowering of a load. The load is raised at the flow rate of the pump, and held until the pump is shut off.
The valve includes 2 male and female components, 2 hydraulic hoses, fittings and dust caps. The valve can also be supplied without couplers, hoses, fitting and dust caps.
The system should not be sized for loads greater than 80% of cylinder load capacity. In addition, to prevent sudden, uncontrolled descent of a load during lowering, use a load lowering valve or counter balance valve in conjunction with the directional valve in your application.
