DIRECT CHECK VALVE

HYDRAULIC SYMBOLS
OPERATING PRINCIPLEMOUNTING INTERFACE
— The MVR valve is a direct check valve made as a modular
version with mounting surface according to the ISO 4401
(CETOP RP 121H) standards.
— It is used to avoid oil backflows and self-emptying of lines,
or to generate back-pressures.
— It can be assembled quickly under the ISO 4401-03
(CETOP 03) directional solenoid valves without the use of
pipes, using suitable tie-rods or bolts.
— It is available in versions with the check valve only on single
line (P, T, A or B) or on both lines (P and T or A and B).

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.
