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 HXM 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.
1.2- Since the HXM valve is used in connection with a high
pressure water pump/system, which shall be called
hereafter only "system", installation and use must be suited
to the type of system used and comply with the safety
Regulations in force in the Country where the valve is used.
1.3- Before using the valve, make sure that the system the
valve is used with is certified to comply with the relevant
Directives and/or Regulations.
1.4- Before installing and using the valve for the first time,
we suggest you check that it is undamaged and make sure
that the rated features correspond to the required ones. If
this is not the case, do not use the valve and contact the
after-sales service of Interpump Group for information.
1.5- In order to install the valve correctly, follow the
instructions for the water inlet, outlet and by-pass
connections, as stated in this instruction manual and/or on
the valve itself.
2- INSTRUCTIONS FOR ADJUSTMENT
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 4).
2.2- Connect the valve to the water system and follow
these steps:
2.2.1- Unloose the adjustment knob pos.12 in order to
completely release the spring.
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,
increase the pressure by screwing down the knob pos.12.
Alternate the adjusting operations with a few openings and
closings of the gun or of the control device.
2.2.4- The working pressure can be reached by completely
screwing down the knob up to contact with the body
pos.16. When the 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.).
2.2.5- It is possible to reduce the working pressure by
removing one or more washers pos.14 and pos.15 from the
valve. Approximately, the pressure decreases by 0.55MPa
(5.5bar) for each washer pos.14 that is removed (thickness
0.2mm) and decreases by 2.75MPa (27.5bar) for each
washer pos. 15 that is removed (thickness 1mm).
2.2.6- After the step 2.2.5, always perform the steps 2.2.3
and 2.2.4 again.
IMPORTANT: Never add washers and/or
shims in addition to those already present
in the valve.
(Pos.14 no. 5 pieces, pos.15 no. 3 pieces)
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.
