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 2000 psi, unless otherwise noted within model code. Relief valve
can be set anywhere within the range of 500 psi to 4000 psi by switching out the relief spring to one of the following:
 500-1100 psi (34-76 bar) – Use spring P/N: S065 (Silver)
 1200-3000 psi (83-207 bar) – Use spring P/N: S059 (Brown, Standard Option)
 3100-4000 psi (214-276 bar) – Use spring P/N: S064 (Blue)
To adjust relief pressure: First, remove the acorn nut with 1/2” wrench. Next, loosen the 1/2” hex jam nut. Using a
5/32” allen wrench on the relief adjustment screw one full turn clockwise will increase pressure by 200 psi.
 Handle Assembly –
L-Style Handle: Place the threaded end of the handle in either hole of the handle adapter and lock handle into
position with the jam nut. Depending on mounting orientation of the valve this will allow the handles to positioned
either vertically or horizontally.
A, A1, A2, A3-Style Handle: Place the threaded end of the handle into the hole of the handle adapter and lock the
handle into position with the jam nut.
FREQUENTLY ASKED QUESTIONS:
Q: Can I plumb another valve downstream from this valve, using the outlet of this valve?
A: You cannot plumb direct to another valve, unless your valve is equipped with power beyond or has been converted to use
power beyond. A valve can be ordered with power beyond already installed by adding a W to the end of the model number.
 Converting valve to “Power Beyond” - Order a power beyond cartridge, P/N: LV2-W. You will then install this
cartridge into the side outlet port. Remove the plug from the top outlet port directly above the side outlet port.
Plumb top outlet port directly back to tank for low pressure fluid.
Q: Can I convert my valve to operate in a “Closed” system?
A: Yes, order a P/N: LV2-C and install it in the side outlet port.
Q: What kits are available for this valve?
A: There is a replacement seal kit (Part #: LV2-SK), and replacement relief kit (Part #: LV2-B2) for this valve. 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
Please note you can order a valve already painted from factoring by adding a P to beginning of model number.
