Directly Operated Pressure
Reducing Valves
HA 5145
11/2012
The pressure valves VRP2 are directly operated reducing
valves for vertical stacking assemblies designed as 3 way
valves, i.e. with pressure protection of the secondary cir-
cuit.
The valve consists of the valve body (1), control spool (2),
spring (3), adjustment element (4) and the plug
G1/4 (5) for pressure measuring
Model “B”
With model “B”, the pressure reduction follows from port
P2 to port P1, but it takes place only when the flow in port
B passes in the direction to the user (not opposite). The
protection of the secondary circuit is also ensured for one
flow direction only.
Model “P”
With model “P”, the pressure reduction follows from port
P2 to port P1, but is effective in both flow directions throu-
gh the directional valve (as well as the protection of the
secondary circuit).
The valves are delivered with basic surface treatment. The
valve body is phosphate coated, whereas the surfaces of
the other parts are zinc coated.

• The plastic packing foil is recyclable.
• The transport plate can be returned to the manufacturer.
• If the valve is used separately without a directional valve, a cover plate DK1-06/32-3 with the same installation
dimensions can be ordered. This plate connect port A1 with port P1 - see catalogue Adapter and Blanking
Plates HA 0003.
• Mounting bolts M5x55 or studs must be ordered separately. Tightening torque of the screws is 8,9 Nm (6.56 lbf-ft).
• For applications outside these parameters, please consult the manufacturer.
