This number belongs to the proportional relief valve series in the Dipma solenoid valve product line, and similar products also include models such as RQ3-P3/41 and RQ3-P6/41
Dipma is a professional hydraulic component manufacturer, and its relief valve products are widely used in industrial hydraulic systems, with pressure regulation and system protection functions.
Number structure analysis
The Dipma product number usually includes the following parts:
The prefix “RQ3” indicates the product series (proportional relief valve)
P5 “: may represent interface size or pressure rating
’41’: may refer to a specific feature or configuration version
Similar numbers, such as RQM5-P5/A/60N-D24K1, also follow the same naming convention
Technical features
As a proportional relief valve, this model should have the following characteristics:
Electromagnetic proportional control method

Plate installation
RQ3-P ISO 6264-06 (CETOP R06)
RQ5-P ISO 6264-08 (CETOP R08)
RQ7-P ISO 6264-10 (CETOP R10)
This valve is a pilot operated relief valve, and the main valve adopts a cylindrical valve core and a cone seal.
Plate installation complies with ISO 6264 (CETOP RP 121H) standard.
The X port can be used as a remote pilot port (see hydraulic symbol table).
The RQ * – P valve allows the full flow of the pump to pass through when the system pressure approaches the set value of the relief valve.
A wide oil passage can reduce pressure drop and improve energy efficiency.

hydraulic oil
When using mineral hydraulic oil HL or HM that complies with ISO 6743-4 standard, use NBR seal. For HFDR oil, use FPM seal (code V). When the working oil temperature exceeds 80 ° C, it will cause rapid aging and deterioration of hydraulic oil and seals.
adjustment knob
RQ type valves can be equipped with SICBLOC adjustment knobs. When operating, the knob should be pressed and rotated. If necessary, add option M to the order model.
