I purchased this valve for controlling a hydraulic wheel motor. Everything works fine but I would like to remove the detent and convert it to closed center so the motor will "park" when not working. Would you be able to help me convert the valve I have or point to the correct one?
A: Please contact our Product Support department to discuss an appropriate replacement. These valves are not convertible from motor spools (work ports open in neutral) to cylinder spools (work ports blocked in neutral)

Would this valve work for operating a double acting cylinder in a press at variable speeds?
A: The work ports are open to tank in neutral so a cylinder would not hold a load in neutral, which may not be an issue on the press, but possibly on the retract.

I purchased a 9-7860 but need a valve that is fine metering and blocks the ports when in the neutral position for controlling a motor. is there a kit to convert this to the operation of the 9-7861(seems like this part does what I need)?
A: There is no kit available to convert one valve body to the other. 9-7861 is a cylinder spool and would have the work ports blocked in neutral. The metering may not be as fine as you would like. Item 9-5174 is a fine metering friction detented (meaning you could take your hand off the handle and the spool would stay in place until moved) spool that does block the work ports in neutral.

I'm need a valve that has 2 spools. One for a motor and one for a cylinder. Can you recommend one?
A: The only way to get a valve with a cylinder spool and a motor spool is to build a stack valve to suit. We carry Prince's SV series and 20 series. You specify the type of system and choose the type of spool you desire, then assemble it when it arrives. Check your system's flow and pressure to determine which series may work best for you.
