6.1 How to regulate the pressure control valve
In order to verify the setting of the valve, you have to proceed as follows:
1. Connect a manometer (with the scale 300-400 bar) to a capillary hose 8-10 m long
to get the working pressure from a safe distance.
2. Install the other extremity of the hose with the plug “P.P.”
3. Operate the hammer and check the working pressure on the manometer.
If the pressure is lower than what indicated by the manufacturer (see par. 2.2 “Technical features”)
you have to:
A. Remove the plug “H”
B. Take off the spring “C”
C. Insert, between the spring “C” and the collar of the small piston “D”, the necessary number
of washers “E”, until the correct working pressure is achieved. In order to know which is the
correct number of washers to add, you have to consider that
one washer
makes a variation
on the working pressure of
7 bar
. The washers must have the following characteristics:
thickness 0.5 mm, Øi=14mm, Øe=21.8 mm.
If the measured working pressure is higher than what indicated by the manufacturer (see par. 2.2
“Technical features”) you have to:
D. Repeat the same steps mentioned above (A+B);
E. Remove the necessary number of washers to get the right working pressure as explained
above.
