Selenoid valves

[Robert128]

These valves are on a Toro Reel Mower. The (I think it is called a Subplate) has one high pressure line in. On the output side - lines run to 3 in-series hydrualic motors (Which have a proportional dial switch for speed control) the other line out goes to a set of 3 hydraulic cylinders that lift the cutters - Operated by a two way joystick.
I am just in the planning stages for this machine. I want to eventually add a rotary cutter to the front and I only have limited funds so I am trying to be creative on using the things that are already there. However, The wiring for the selenoid valves go back to a central controller box. I am just trying to decide if there is any way I can use these valves or if it might be better to take them out and use manual valves. Thanks for all of the information on selenoid valves. It helped.

I guess that answers the proportional part!:confused2:

I believe the solenoid valves are used to select on or off to the hyd motors, and that is the way most hyd mowers work. I can think of no reason to vary the speed of hyd motors when mowing. There are valves made for flow control, and I have one of those on my PTO circuit.

I would at least give it a try. You have a controler box, valves, and it was off of a mower.

even if we dont need to feather the operation speed on a mower, we might need the prortional valve to autmaticaally ramp the start up of the motors....still on-off but featherd at star....to save us from "killing" the engvine......
