Parker counterbalance valves are screw-in type cartridge valves that control the pressure at an actuator controlling its motion. Uses include controlling over-running loads in cylinders and

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.

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

Danfoss offers dual counterbalance valve HIC . Find mode codes and 3D model codes.

18/03/  · Learn how a counterbalance valve works! Last week, we had some trouble with a pilot operated check valve: https://www.youtube.com/watch?v=Frn3f1WZdLM. This w

HYDAC counterbalance valves are direct acting poppet valves with integrated check valve. Indeed, they enable a jerk-free movement on the part of consumers in the presence of over-centre loads. Furthermore, it leads to: Avoidance of a hurrying ahead of the pulling consumer. Preferred application for safety and control tasks with double acting

26/08/  · A counterbalance, or load-holding, valve is a mechanism typically located near the actuator that uses hydraulic pressure to keep a load from moving. Generally, these valves have

If a load must be controlled while in motion, a counterbalance valve should be used. For this reason, counterbalances are often referred to as “motion control 

Describe the schematic symbol for an external drain. Identify customary locations for the 5 main pressure control valves. Describe a counterbalance valve using 

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.)

Counterbalance valves should be set at least 1.3 times the maximum load induced pressure. Turn adjustment clockwise to decrease setting and release load. Full clockwise setting is less than 200 psi (14 bar). Backpressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the backpressure.

Description. Counterbalance valves are used in hydraulic systems working with an overriding (run-away) or suspended load. They are designed to create backpressure at the return line of the actuator to prevent losing control over the load. The following illustration shows a counterbalance valve schematic.

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

Counterbalance valves are used to prevent oil from leaving a cylinder that is holding a load. Without the counterbalance valve, the load would move in an uncontrollable manner if oil pressure is lost for some reason. In a sense, they act as adjustable pressure relief valves and are often used where line pressures can spike.

22/05/  · The counterbalance valve is located in a line between a directional control valve and the vertically mounted actuator/cylinder. The counterbalance valve working principle states

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.

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

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

Counterbalance valves setting corresponds to the opening pressure of pressure relief section. This pressure determines the max load which counterbalance valve
