Counterbalance valves can be used with paired cylinders: pilot pressure will open first the valve of the most heavily loaded cylinder; this will cause load transfer to the other cylinder and the related valve, still closed, will require less pilot pressure for opening.

Counterbalance Valve With Test Harness. This example shows how to model, parameterize, and test a counterbalance valve. When you run the model, it generates a plot of the flow from the load port to the back port due to the relief action of the counterbalance valve. A counterbalance valve allows an upstream flow from the back port to the load

As the industry leader in counterbalance solutions, Sun Hydraulics offers more than 150 standard counterbalance models in a range of capacities, pilot ratios and configurations. The proven CB** family of valves leverages a proven poppet-and-piston design suitable for most general applications and provides precise, reliable load holding and motion control at an affordable price.

The counterbalance valves block flow from returning to the reservoir, thus holding the actuator in place. The valve actuator represents the electromagnets that control the directional valve position. When electromagnet B is energized, the directional valve is in the negative position and connects ports A and B to the pressure port P.

12/12/  · A counterbalance valve (also called a brake, holding and/or overcenter valve) is a normally closed-pressure control used to oppose the pressure created by a load. They are typically either internally piloted or internally and externally piloted. When used for holding, these valves must be direct acting, poppet-type pressure controls so valve

A counterbalance valve is a combination of a pilot operated relief and a reverse free flow check valve. When utilized as a load holding valve in a hydraulic cylinder application, the free flow

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