Counterbalance valves can be compared to elevator counterweights. A heavy elevator car is tough for a motor to start and stop on its own. Without a counterweight, raising or lowering the car is tough! The motor and drawworks have a hard time starting and controlling the load. Elevator Without Counterweight. Elevator With Counterweight.

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

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.

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

Values in the US customary unit system are converted and rounded values. In case of doubt, only metric values are valid.

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