The pressure valves VRN2 are pilot operated screw-in
cartridge pressure reducing valves designed as 3 way
valves. For the use in vertical stacking assemblies, three
models of valve bodies are available, with pressure
reduction in ports A, B and P. Incorporated into the valve
bodies MA, MB are the check valves which enable the
reverse flow to pass through the valve.
The reducing valve consists of a cartridge (1) with thread
M27x2, control spool (2), spring (3) and the adjustment
element (4). With the models for stacking assemblies
also the respective valve body (5) and alternatively a
check valve (6) complete the valve.
Screw-in cartridge valve
At rest, the valves are open, i.e. oil can flow from input
line via the main spool to output line . At the same time
there is pressure from output line via the main spool
with bore and jets and at the spring-loaded side of the
main spool and at the side opposite the spring. If
pressure in output line exceeds the value set at the
spring the pilot poppet opens. Oil now flows from the
spring loaded side of the main spool vis the jet and pilot
poppet into the chamber. The main spool moves into
control position and holds the value set at the spring in
output line constant. If pressure behind the valve
increases due to the effect of external load acting on the
user, the control spool shifts further against the spring,
the input line closes and the flow from output line to port
T opens. The control flow of the pilot valve (from the
spring room) is also routed to port T.
Model MA and MB
With these models, the flow enters into the valve body
through port A1 (B1). The input pressure is reduced,
routed to port A2 (B2) and further to the user. The
reverse flow passes through a check valve which is
connected parallel to the metering edge.
Model MP
With the model MP, the pressure is reduced from port P2
to port P1. With all models, a control pressure gauge can
be connected to port G 1/4 (7).
The screw-in cartridge valve body and the adjustment
screw are zinc coated. With models for stacking
assemblies the valve bodies are phosphate coated.
