SOLENOID OPERATED PRESSURE
RELIEF VALVES WITH UNLOADING
AND PRESSURE SELECTION
SERIES 60
21 310/112 ED
OPERATING PRINCIPLE
— The RQM*-P valves are pressure relief valves
available in three nominal sizes for flow up to 500
l/min.
— They are available in ISO 6264 (CETOP RP 121H)
subplate mounting version.
— Available in five versions that allow, by means of a
solenoid valve, unloading of the total flow and
selection up to three pressure values (see table 2
Versions).
— The adjustment of the second and third pressure
values is obtained by a pressure relief valve placed
between the main stage and the solenoid valve.
— It is supplied with an hexagonal head adjustment
screw. Upon request, it can be equipped with a
SICBLOC adjustment knob on the main pressure
control.
NOTE: for the solenoid valve DS3 characteristics see catalogue 41 150

4 - HYDRAULIC FLUIDS
Use mineral oil-based hydraulic fluids HL or HM type, according to ISO 6743-4. For these fluids, use NBR seals (code N). For fluids HFDR type
(phosphate esters) use FPM seals (code V). For the use of other kinds of fluid such as HFA, HFB, HFC, please consult our technical
department. Using fluids at temperatures higher than 80 °C causes a faster degradation of the fluid and of the seals characteristics.
The fluid must be preserved in its physical and chemical characteristics.

(see catalogue 51 000)
7 - ADJUSTMENT KNOB
The valves can be equipped with a SICBLOC adjustment knob, only on the main pressure regulation.
To operate it, push and rotate at the same time.
To request this option, add: /M (see paragraph 1).
8 - ELECTRIC CONNECTORS
The solenoid valves are never supplied with connector. Connectors must be ordered separately. For the
identification of the connector type to be ordered, please see catalogue 49 000.
9 - MANUAL OVERRIDE, BOOT PROTECTED: CM
Whenever the solenoid valve installation may involve exposure to atmospheric agents or utilization in tropical climates, use of the manual
override boot protected is recommended.
Add the suffix CM to request this device (see paragraph 1). For overall dimensions see catalogue 41 150.
