Pressure Relief Valves
Important Information regarding Pressure Relief
Valve 16C807.
Pressure Relief Valve 16C807 can only be used on
the G1 and G3 Pumps. It is not intended for use with
any other products.
The pressure relief valve uses a
pressure adjustment screw (a) to
set the pressure 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
unintended pressure increase in
the system. Do not use this pres-
sure relief valve a means of
relieving pressure in day-to-day,
normal cycle operation.
The pressure adjustment screw
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 bot-
tomed 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.
