If you are driving a 90S EDC (KA) then never put 12V directly to it. You don't need more than 2.5V to get to max flow. Anything >6-7V increases service business ($$$).
If you are using a 90S EDC compliance block with the currents set correctly (14-85mA) then you don't need to worry about supply volts. The PWM duty shifts accordingly to control the current.

Thanks,

That’s kind of what I was wondering, yes I’m using a 90l130 with edc control set up as 14-85mA and kind of wondered if the Pwm would take care of it, so in your opinion 24vdc supply voltage is fine? I guess I should connect both coils for as much impedance as possible?

Thanks

Matt

tronelec:
in my experience the problem will be the other way around if the actuator is 24 volt and your source is 12 volt, but the actuators for pumps consume very little current, if you don't over do the current there would be no problem, what if the curve changed relationship between current versus flow

@matttargett4 Yes 24V is fine.
