If this is not the proper group, where should I post such a topic?
I have a smail tractor mounted hydraulic crane where the control valve
assembly is a bit worn. Instead of just spending a lot of money in
getting a suitable 'manual' control valve assy I consider checking a
bit around to see if I can find a surplus electric proportional
hydraulic control valve assy for at least 4 double-acting cylinders
and replace my old control valves with this electric version. (I don't
want wireless remote control, only wire)...
Are there different types of electric proportional valves for doible-
acting cylinders or would almost any model do? (Given that flow and
pressure are supported).
However despite that I work a lot with electronics I don't know how
the solenoids normally are interfaced with the control pots. Do they
use an electronic module between the joysticks and the solenoids which
varies the current between the solenoids according to the position of
the joystick, or is this circuitry normally included in the joystick
assy? Thanks for some comments on this.
Does anyone here have suggestions on where to obtain such surplus
Other relevant comments and suggestions are highly appreciated :-)
