counterbalance valve

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 

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

Our family of M-valve Load-Reactive Load Control valves offers improved modulation performance. Functionally, it is a counterbalance valve that seats as a poppet valve and modulates as a spool valve, offering the best of both worlds. A built-in dampening device smooths the opening of the valve while allowing the valve to close quickly.

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

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 (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.

Parker's CB series counterbalance valve operates as a pressure relief valve. The setting pressure is lowered by the pressure in the inlet line. The return flow from the actuator is piloted and controlled by the inlet flow to the actuator, ensuring a cavitation-free lowering load.

The products are designed and developed in parts in body (Overcenter), these valves are characterized by mechanical moving parts that 

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. If a directional valve (not shown in the picture) is

The proven counterbalance valve series ZNS in size NG06 (CETOP 03) and NG10 (CETOP 05) enables a reliable operation by controlling the actuator movement at overrunning loads. 20 Parts Viewing 10 of 20

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 valves are also used to prevent a loaded cylinder from falling, but their operation is smoother than a pilot-operated check valve

07/03/  · A counterbalance valve would allow the downward movement of the load supported by a cylinder only when the system pump is operating. The force generated by the system

16/12/  · Counterbalance valves have no pilot ratio and rely purely on line pressure to open them. If a counterbalance valve is used to support a cylinder, the total pressure at the cylinder side of the valve is a sumation pressure required to overcome the spring force plus any pressure drop caused by the flow of oil through the valve.

Learn how hydraulic counterbalance valves work. Understand the different types of valve that are available, their function and where they are used.

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 

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

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

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

loads less pilot pressure to open the counterbalance valve, helping to improve stability and reverse flow check valves are suitable for counterbalancing.

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