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 3000psi.
To adjust relief pressure: First, remove chrome hex plug next to the inlet port with a 7/8” combination wrench, etc.
You will then have access to the relief set screw. Turning this screw with a 5/16” allen wrench clockwise ¼ turn will
increase pressure approximately 200psi.
 Hydraulic Kick-out Adjustment – The SH & SHA models have an adjustable single hydraulic kick out preset to 800-
1000 psi. The HHA model comes equipped with a double hydraulic kick out preset to 800-1000 psi.
To adjust kick-out pressure: Locate jam nut, and set screw on the spool action cap. (Opposite valve’s handle)
Loosen jam nut, and turn set screw. Turning set screw clockwise with a 1/8” allen wrench will decrease kick-out
pressure, while turning it counter clockwise will increase kick-out pressure on the SH version of valve.
 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 spool 180º .
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: Which port has “Hydraulic Kick-out”?
A: The ‘A’ port (See Dimensional Data) will, when handle is engaged in a detent position until the kick-out pressure is
reached, at which point the valve will “kick-out” of detent into the neutral position.
Q: What kits are available for this valve?
A: There is a replacement seal kit per valve. Valves ending in SH uses LS-RK, valve ending in SHA uses LSJRSH-K, valve
ending in HHA uses LSJRHH-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.
