Need advice on proper name for a flow reversing spool valve
(OP)
Hello I am trying to identify if a certain type of hydraulic spool valve exists and what the proper name for it would be. So far on my internet searches I have not been able to find what I am looking for. I am looking for a 24V two position solenoid actuated spool valve block that has 3/4 " NPT or 1" NPT or equivalent machine thread ports. It needs to be acceptable for 3000 psi hydraulic service. It needs to have 4 ports. Port A = pressure supply, Port B =Tool fwd flow , Port C =Tool reverse flow, Port D = drain to hyd sump. With this spoolvalve unactuated flows A to B tool spins fwd tool discharges to port C which is connected to D = drains to sump. Then when spool valve solenoid is actuated Port A connected to C tool spins reverse, tool discharges to port B connected to D drain to sump.
Summary Unactuated A to B, C to D. Actuated A to C, B to D
I have tried flow reversing spool valve, cross flow valve, several other ideas with no luck. Any ideas if such valve is available. Thanks, Dan

The GPM rating may be misleading.

The valve data will tell you what pressure drop you get for your flow rate.
You will be well advised to check the pressure losses, then you won't be back here in a few weeks/months asking why you don't have enough power to run the system.

Coils are available for most valves with 24 volt coils.
