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
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 R1510 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.
2- INSTRUCTIONS FOR INSTALLATION AND PRESSURE
SETTING:
The positions mentioned in the following instructions refer to
those shown in the spare parts catalogue (page 4).
2.1- Installation
2.1.1- Fit the O-Ring pos. 30 into the seat of the valve body pos.
11.
2.1.2- Set the valve on the pump head taking care that the O-Ring
pos. 30 stays in place correctly.
2.1.3- Slightly lubricate the threads of the four screws pos. 40 with
Lithium grease and tighten by means of a dynamometric wrench
(torque wrench setting as stated in the exploded view – drawing
A).
2.1.4- In order to obtain the sealing between the nipple pos.44 or
the cap pos.45 and the valve body, use the conical seal pos. 1
(Tab. B – 120Nm). Please contact the after-sales service of
Interpump Group in case of doubts.
2.1.5- 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.
2.1.6- Connect the valve to the water system and to the pneumatic
circuit, then follow these steps:
2.2- Pressure setting
2.2.1- Unloose the adjustment screw pos. 24 in order to
completely release the springs.
2.2.2- Open the gun or the water control device and start the
system. Make sure that the air contained in it is fully ejected.
2.2.3- Keeping the gun or the water control device open, start
adjusting the pressure by screwing down the screw pos.24.
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.
2.2.4- Screw down the nut pos. 34 up to contact with the body, in
order to lock the screw pos. 24.
2.2.5- In order to obtain working pressures lower than the
maximum set pressure, unscrew the screw pos. 24.
In case of doubts, do not hesitate to contact the
after-sales service of Interpump Group.
IMPORTANT: During use, never exceed the
maximum values of pressure, flow-rate and
temperature as stated in this document and/or
indicated on the valve.
3- WARNINGS
3.1- For safety reasons, it is advisable to equip the high pressure
feeding line of the system also with a relief or safety valve duly
adjusted.
3.2- Tighten the fittings for the valve connections as follows:

G3/8" G3/4" M14x1,5 M20x1,5 M22x1,5 M24x1,5
3.3- In order to optimize the pump-valve coupling, it is necessary
to keep the valve operation range, as a function of the pump
pressure and flow rate, within a maximum power of 170 kW (231
HP). As shown in the chart, this means using pumps producing a
flow rate of approx. 60 l/min. for maximum working pressures of
150 MPa (1500 bar - 21755 psi), and generating a pressure of
approx. 68.5 MPa (685 bar-9933 psi) for maximum flow rates of
130 l/min.
