Hello All,

Newbie here. I am an electrician with 34 years experience but don't know much about hydraulics. I would like to know what type of solenoid operated valve opens 2 ports at the same time. I need one to feed a cylinder (Seastar) to steer a outboard motor that is used for trolling. Valve must be closed when not energized and fluid must be able to flow both ways when open.
...........................VALVE
from helm pump <--->| |<---> to cyl (steer to port)
from helm pump <--->| |<---> to cyl (steer to starboard)

Please advise,
Thank you,
Dennis in Michigan

DriverDennis,

I suggest that you use a two sectional electromechanical flow control valve with flow compensator on each section to drive each of your function individually, this will allow you to operate either both the pilot controls at the same time or individually. You can find this kind of valve with any hydraulic components manufacturer such as Parker, Rexroth, Husco etc.

Yes the valve will be in a closed state when not energized, you can figure this in your electrical work.

Hydraulic systems are very similar to that of electrical systems and they also use the same terms such as parallel, serial etc. The valve I mentioned above is a parallel system.

Electrical system: Electrons flow in wires.
Hydraulic system: Oil flows in the hydraulic lines.

By following the above comparison you can easily learn hydraulics.

SDK.

"orbital" valves do this, steering valves on mining equipment

where is a good source to get one? thanks.
