Double acting counterbalance valve is designed to hold and control the load lowering on the corresponding working body (hydraulic cylinder).

08/02/  · GPM Instructor/Consultant Alan Dellinger explains the symbol, operation, adjustment and troubleshooting of the often misunderstood counterbalance valve. Visi

Important factors when specifying counterbalance valves are:- Line lengths; Trapped Air; Cylinder stick/slip; Setting the Valve

Counterbalance valves allow raised loads to be lowered safely, with a minimum of wasted energy. The Counterbalance Valves lesson provides a thorough look 

A counterbalance valve can easily be described as a pilot operated relief valve with a free flow check. The relief valve within the counterbalance valve provides the critical function of

The counterbalance valve offsets the potential energy of the weight on the rod end of a cylinder. The 15,000-lb force in this figure cannot do useful work when using an internally piloted counterbalance valve. (See Figures 5-13 through 5-15 for energy loss and heat generation for different types of counterbalance circuits.)

So basically a counterbalance valve is a hydraulic system pressure control valve that is used as a safety device to prevent the movement of a
