HBS rotation control valves

These valves are utilised to control the stop and the motion of cylinders and hydraulic motors for the rotation of hanging loads. Symmetrical capacity of both the rotation direction is typical of motors and cylinders for this application.

The valves can be composed by:

- dual crossed relief pressure valve: it controls any pressure peaks coming from overloads or shocks that could damage the system components;

- motion speed control valves: for this operation restriction check valves or pressure compensated flow control valves are utilised;

- load hold valves: for this task overcenter valves or check valves are utilised;

- a pressure selecting valve that picks up the signal from the highest pressure side.
