In this edition of Newsletters that Teach we will cover the basic function of a counterbalance valve. Counterbalance valves are also often referred to as motion control valves and over-center valves. All three names address the important function of these valves.They are deployed in applications where hydraulic cylinders or motors are working against gravity in one direction, and with gravity (sometimes called a negative load) in the other direction.
