3/4”NPT Inlet/outlet and 1/2” NPT work ports.

#12SAE Inlet/outlet and #10SAE work ports.

• 30 – Micron filtration recommended.

MOUNTING, ADJUSTMENT & ASSEMBLY INSTRUCTIONS:

 Mounting – Valve can be mounted in any orientation. Valve must be mounted on a flat surface. Special attention should

be paid to not bend or twist the casting when mounting. Doing so may cause the valve to fail.

 Relief Adjustment – Relief setting is factory preset to 1500 psi, unless otherwise noted within model code. Relief valve

can be set anywhere within the range of 500 psi to 3000psi.

To adjust relief pressure: First, remove chrome hex plug next to the inlet port using a 7/8” combination wrench,

etc. and set aside. You will then have access to the relief set screw. Turning this screw with a 5/32” allen wrench

clockwise ¼ turn will increase pressure approximately 200psi.

 Handle Assembly – Regardless of handle style, the handle retainer will be installed on valve from factory. Unless

specified, the retainer’s placement is defaulted so the handle points up when the valve is placed on a flat surface. To

change this, prior to handle installation, the screws holding the retainer must be removed and the retainer can then be

rotated around the valve in 180º increments.

L-Style Handle: Recognized by the single hole in the end of the spool, place the ball end of the handle in the spool

and then join the handle and the retainer using the supplied pin.

J-Style Handle: Recognized by the single slot in the end of the spool, first, place a pin thru the bracket welded to

the retainer and secure with a pin clip. Next, place the C-notch of the handle over and onto the pin. Finally, align the

hole of the handle with the hole on the spool and secure both together using the second pin and clip.

FREQUENTLY ASKED QUESTIONS:

Q: Can I plumb another valve downstream from this valve, using the outlet of this valve?

A: No. The outlet of this valve should be plumbed back to tank.

Q: If my current valve does not have a relief included, can I add one?

A: You cannot add a relief to an AO valve that does not have a relief factory installed

Q: What kits are available for this valve?

A: There is a replacement seal kit (Part #: SDC-K) There are also a number of different kits available for this valve

depending on the spool action, and handle option the valve is equipped with. Please contact factory for specific kit numbers

relating to different spool actions, and handle options.

Q: Can I paint the valve?

A: Painting valves is acceptable as long as the following precautions are taken:

1- All ports must be plugged

2- Spool must be masked or taped off completely.

Any paint on the spool will cause leakage when it chips off. Warranty is void if any valve is returned with paint on

the spool.
