Controls. Hydraulic-mechanical CA

The HPV-02 CA is a speed-dependent pump control with torque/power regulation. It can be combined with a hydraulic motor as
fixed, variable or regulating motor or a variable motor with pressure regulator. The modular design offers a high degree of versa-
tility in terms of function and control.
