ruptured components will pierce skin. This may look like
just a cut, but it is a serious injury that can result in
amputation. Get immediate surgical treatment.

Pressure Relief Valves
The pressure relief valve
uses a pressure adjustment
screw (a) to set the pres-
sure release point. It is not
intended as a way to
relieve pressure during
normal operation but as a
protective measure in the
event there is an unin-
tended pressure increase in
the system.
NOTE:
•
Do not use this pressure relief valve as a means
of relieving pressure in day-to-day, normal cycle
operation. Use the pressure relief procedure
described on page 3 of this manual to relieve
pressure during normal cycle operation.
•
The pressure relief valve included in this kit can
only be used with the Graco G3 Pump. It is not
intended for use with any other products.
•
Factory set to 4000 psi (275.8 bar, 27.6 MPa).
The pressure adjustment screw (a) will require periodic
adjustments. Whenever the valve is set/adjusted (after
the set point is found) it is important to ensure that the
valve is not bottomed out and there is at least 1/2 turn of
adjustment remaining. This is determined by turning the
screw (a) 1/2 turn and then back turning it out again.
NOTE: Turning adjustment screw (a) clockwise,
increases pressure.
