Pilot operated pressure relief valves series R4V (DIN
24340 Form D) and R6V (DIN 24340 Form E) consist of
a manually adjusted pilot stage and a seated type main
stage.
A vent function with a solenoid operated directional valve
is available for circulation at minimum pressure.
Features
• Pilot operated with manual adjustment
• 2 interfaces
- R4V Subplate ISO 6264 (DIN 24340 Form D)
with VV01 vent valve
- R6V Subplate ISO 6264 (DIN 24340 Form E)
with Cetop 03 vent valve
• 3 pressure stages
• 3 adjustment modes
- hand knob
- acorn nut with lead seal
- key lock
• Remote control via port X
Characteristics
Function:
Series R4V/R6V
System pressure in port P is applied via the X gallery to
the spring loaded cone in the pilot head. The pilot head
controls the pressure in the Z area on top of the main
cartridge which is additionally kept close by the main
spring.
If the pilot pressure exceeds the setting pressure the pilot
cone opens and thus limits the pilot pressure.
When the system pressure exceeds the pilot pressure
plus the spring force, the main cartridge opens to port T
and limits the pressure in port P to the adjusted level.
Series R4V/R6V with vent function
Additionally to the relief function of series R, a solenoid
operated vent valve connects the Z area to tank. This
allows oil circulation from P to T at minimum pressure
drop. The vent valve can either be a standard Cetop 03
valves (mounting form E) or a sandwich unit (mounting
form D). For both types the vent position can be either at
the energized or de-energized solenoid.
