11-2. Relief valve set up
The MDG-R2( )V model is equipped with a built-in relief valve.
The pressure set upon shipping is 0.4MPa. The pressure value can
be adjusted within the range of approximately 0.3~0.4MPa. Prior
to resetting the pressure, please contact us and follow the procedure
described below.
[1]
Loosen the clamp nut (1) with a spanner (M4).
[2]
Adjust the pressure for the desired value by turning the set pres-
sure adjustment screw (2) with a flat head driver (Watch the
pressure gauge installed on the discharge piping in advance for
reaching the target value.)
[3]
Fasten the clamp nut (1) tightly with the spanner (M4). Be sure to
check for liquid leakage after resetting the relief valve.
(Note) The pump performance varies with the relief valve pressure
set point.
