This little valve is intriguing, but for most applications you would need to switch both lines for complete control, and that
one does not do that from what I can see.
Sorry, I thought you had used the 2-solenoid manifold-type valves before. HydraForce calls those "sandwich valves".
I am a proponent of the simplest and/or most economic solution, so I like this HydraForce valve if someone wants
to switch 2 hydraulic circuits simultaneously. It is a simple 2-position valve that requires only one solenoid
to control it. I have posted the hydraulic schematic here to show how simple it is.
The large 2-solenoid valves sold by SurplusCenter, WRLong, and others have 3 positions with an open
center at neutral. One solenoid pushes the spool, and the other pulls it.
This HydraForce valve is bidirectional so needs only 2 positions and DOES switch two lines
for complete control.
At the risk of getting into the weeds here, these solenoid valves can only push or pull, not both,
and generally don't care about polarity.
