HYDRAULIC SYMBOL
OPERATING PRINCIPLEMOUNTING INTERFACE
— The MVR-RS/P valve is a check valve that incorporates
also the function of flow restriction.
— It is made as a modular version with mounting surface
according to the ISO 4401-03 standards.
— It can be quickly assembled under the ISO 4401-03
directional solenoid valves and modular valves, without
use of pipes and using suitable tie-rods or bolts.
— It is used when it is necessary to control the flow in a
direction and to avoid backflows or the self-emptying of
the lines in the opposite direction.
— Control of the flow is obtained with a countersunk hex
screw with locking nut.

3 - HYDRAULIC FLUIDS
Use mineral oil-based hydraulic fluids HL or HM type, according to ISO 6743-4. For these fluids, use NBR seals. 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.
