Proportional actuator blocks for direct connection on HCD (HYDROCONTROL) and SD (WALVOIL) hydraulic valves, were born to allow the remote control of a machine, which has these kinds of manual hydraulic valves: each module for HCD-SD that is part of the block can control one proportional function.
The direct installation on the back of the hydraulic valve guarantees the possibility for the user to make a very “precise” mounting, in a “limited” place. In this way risk of any eventual future “mechanical plays” is excluded.

The installation of our proportional modules for HCD-SD hydarulic control valves really is a simple operation. In this tutorial, we explain all the procedure in only 10 steps!
