THIS DOCUMENT PROVIDES THE INSTRUCTIONS FOR THE
INSTALLATION, USE AND MAINTENANCE OF THE VALVE,
THEREFORE IT IS AN INTEGRAL PART OF THE VALVE
ITSELF AND MUST BE READ CAREFULLY BEFORE ANY
USE AND KEPT WITH CARE.
STRICTLY COMPLY WITH THE INSTRUCTIONS CONTAINED
IN THIS DOCUMENT IN VIEW OF A SAFE AND EFFECTIVE
USE OF THE VALVE.
FAILURE TO COMPLY WITH THESE INSTRUCTIONS MIGHT
CAUSE EARLY FAULTS AND RESULT IN SITUATIONS OF
DANGER, IN ADDITION TO VOIDING ANY WARRANTY.
1- GENERAL INFORMATION
1.1- The R1102 pressure regulator is a manually-
adjustable, pressure-operated device which, according to its
setting, limits the pump/system pressure by conveying the
excess of water to the by-pass.
Moreover, when the outlet flow is blocked, this device totally
releases the flow, thus keeping the pump/system at the
adjusted pressure +15%.
2- INSTRUCTIONS FOR PRESSURE SETTING:
2.1- In order to obtain a correct adjustment and
consequently a proper functioning of the valve, always
make sure that, when working at the maximum pressure,
the valve by-pass keeps releasing a quantity of water equal
to 5% of the total flow-rate. In case the flow-rate at the by-
pass is close to zero or exceeds 15% of the maximum flow-
rate, this could cause faults, early wear and result in
situations of danger.
The positions mentioned in the following instructions refer
to those shown in the spare parts catalogue (page 3).
2.2- Connect the valve to the water system and follow these
steps:
2.3- How to adjust the valve for the first time after
:
installation
2.3.1- Unloose the adjustment screw pos.22 in order to
completely release the spring.
2.3.2- Open the gun or the water control device and start
the system. Make sure that the air contained in it is fully
ejected.
2.3.3- Keeping the gun or the water control device open,
start adjusting the pressure by screwing down the screw
pos.22. Alternate the adjusting operations with a few
openings and closings of the gun or of the control device.
When the desired pressure has been reached, open and
close the gun/control device a few times again in order to
stabilize the various components (seals, springs etc.). Check
the pressure value again and correct if necessary.
2.3.4- Lock the screw pos. 22 by tightening the nut pos. 23.

2.4- Following adjustments:
2.4.1- WARNING: In order to obtain an accurate
adjustment and to avoid residual pressure inside the
valve and the system, make sure that the system is
turned on and under pressure before using the screw
pos. 22.
2.4.2- Follow the instructions of point 2.3.3 turning the screw
pos. 22 clockwise or counterclockwise in order to increase
or decrease the pressure.
2.3.4- Lock the screw pos. 22 by tightening the nut pos. 23.
3- WARNINGS
3.1- Use guns or other control devices ensuring a perfect
seal when closed. Leakages may compromise the correct
functioning of the valve.
3.2- Before installing the valve, slightly lubricate the G3/8
thread with a grease specific for very high pressures (EP-
extreme pressure) containing Graphite or Molybdenum, then
tighten the fitting by means of a dynamometric wrench 200
Nm.
3.3- Before operating the system, it is advisable to start it for
a preliminary test run in order to check that the system is
properly installed.
