Elektrohydraulic mobile proportional valves
series HPV44 to Q max = 140 ltr/min
as well HPV77 to Q max = 240 ltr/min

They are for mobile uses
pmax = 300 bar.

It gives the variety of instruction near piston functions.

The control follows to choice with proportionality of coil, with or without coupling manageable, with black / whiteness of coil, or from hand.
