PLEASE NOTE:
BEFORE REMOVING VALVE SPOOL OR SPOOL SLEEVE REMOVE DETENT
ADJUSTING CARTRIDGE, DETENT PISTON AND STEEL BALL. INSERT SPOOL AND
SPOOL SLEEVE BEFORE INSERTING STEEL BALL.
PRESSURE RELEASE DETENT
This feature provides a pressure release detent for the spool "out" (handle in) position.
When the spool is manually placed in the detent position oil is directed to the 'B' port (the port
away from the handle). When the pressure in the 'B' port reaches a preset level the detent
will release and the spool will centre. The factory setting is 1400 psi. The detent release
pressure is adjustable by loosening the jam nut turning the adjusting screw. Turning the
adjusting screw clockwise will increase the detent release pressure and counterclockwise will
decrease the detent release pressure. NOTE: if the detent release pressure is set too high
the spool will not centre. If the pressure is too low the detent will not hold. If cap screw (#6)
becomes loose detent will not function properly.
RELIEF VALVE
An adjustable ball spring relief valve is standard on all Hydrasplitter hydraulic valves. The
standard factory setting is 2250 psi @ 3 gpm and 120°F.
Other settings can be specified.
The relief pressure is adjusted by removing acorn nut, and turning the adjusting screw.
Turning the adjusting screw clockwise will increase the pressure and counterclockwise will
decrease the pressure (a pressure gauge must be installed in the inlet line whenever the
relief pressure is adjusted). Do not back out adjusting screw to the point it falls out.
WARNING: OVERPRESSURE MAY CAUSE SUDDEN AND UNEXPECTED
FAILURE OF A COMPONENT IN THE HYDRAULIC SYSTEM RESULTING
IN SERIOUS PERSONAL INJURY. ALWAYS USE A GAUGE WHEN
ADJUSTING RELIEF VALVE.
