Unbalanced logic elements

Unbalanced logic elements
Logic elements are available in both balanced and unbalanced versions.

With unbalanced logic elements the pressure from the load is used to open the valve


Unbalanced logic elements are affected by the load in the system. The advantage may be, for example, that you do not need an external pilot source, instead you can use the pressure from the load to open the valve.
