Showing Questions of 11

how to convert open center to closed center please

A: Remove the steel plug directly below the 'C' mark in the casting on the left hand side of the valve with the handle end toward the observer. Install the supplied hollow hex head High Pressure Carryover plug into the threaded cavity on the inner wall of the valve. Replace the steel plug in the exterior wall of the valve. Instructions detailing these locations are on page 2 of the Instructions document on this item's web page. If the supplied High Pressure Carryover plug has been lost or misplaced, they are available as item 9-7867-B.

IN A POWER BEYOND SETUP CAN IMAKE SO THE RELIEF VALVE WILL RELIEF STRAIGHT TO THE TANK?

A: No. The relief cartridge dumps to the return galley of the valve, which should have a path back to tank regardless of its position in the circuit. In other words, the power beyond flow will feed the next valve in the series, and all valves in the series will have return lines plumbed back to tank.

Is this valve available with one spool configured for "float"?

A: No, it is not. That configuration is not offered in this series.

I need to limit pressure to 1000 psi. Can the integral relief be simply modified or do I need to install a separate relief valve?

A: The existing relief does not adjust low enough, and a lower-range relief cartridge is not available. A 500-1500 psi adjustable relief (9-6135-50-L) could be plumbed into the pressure line feeding the valve.

When are you getting more of these? I am waiting on my back order valve

A: We have had two Purchase Orders that have not been fulfilled by their due dates. We are questioning the vendor for an accurate arrival date.

Can you install a joystick and have move a control lever 90 degrees to stick out at the top of valve. I would like to see a joystick and a lever in the same direction.

A: There are threaded holes in the lever attachment ends of the standard hardware that allow for handle mounting parallel to the spool, so if a joystick kit were mounted they would both be pointing the same direction. The alternate threaded holes are visible in the picture of the valve.

Does the Seal Kit (Item 8, Part # 660570003) installed in the valve or purchased separately?

A: The valve comes with the seals installed. The kit is also available for purchase on a special order basis.

To convert to power beyond operation do I need a special sleeve on port "C" In addition to enclosed high pressure carry over plug?

A: No, in this model, the high pressure carryover plug blocks the power core from the return galley. If power beyond is needed, then plumb from port 'C' to the downstream valve. For closed center operation, leave a high pressure steel plug installed in that port.

My tractor has 9.5 gal/min, do I need to step up to the 14 GPM valve to work correctly

A: Yes, you should use a valve that has a listed flow capacity of at least as much as your pump.

Can the handles be disassembled and turned 180 degrees from pictured orientation and point down below the back of the valve housing?

A: Yes, they can.

Can one of these spools be used to operate a single acting cylinder, while the others operate double acting cylinders?

A: If used for a SA cylinder the pump flow is blocked when the lever is shifted causing the oil to have to go over the relief valve. Or you can put a hose from the unsued port to the return line of the valve to prevent this.
