Valves of type 3DRE(M)E are electrically pilot-operated 3-way pressure reducing valves with pressure limitation of the actuator.
They are used for reduction (P to A) and limitation (A to T) of a system pressure.
Set-up
The valves consist of two main assemblies:
Pilot control valve (1) with proportional solenoid (2) and integrated electronics (OBE) (17), optionally with maximum pressure limitation (15). Supply and command value voltage are applied at the connector (16). At the factory, the command value pressure characteristic curve is adjusted with little manufacturing tolerance.
Main valve (3) with main control spool (4)
Function
Command value-dependent setting of the pressure to be reduced in port A via the pilot control valve (1).
With depressurized port P, the springs (5) and (6) hold the main control spool (4) in its central position. In this way, a start-up jump at the actuator is prevented.
Pilot fluid flows from bore (7) via the flow controller (8), via the control chamber (11) to the throttle gap (9), via line (10) to port Y. This connection is to be led into the tank at zero pressure.
Pressure reduction
Build-up of the pilot pressure in the control chamber (11) as function of the command value.
Pressure build-up in the spring chamber (13) via nozzle (12) and movement of the main control spool (4) to the right. Hydraulic fluid flows from P to A.
The actuator pressure in port A is available in the spring chamber (14).
Increase in the pressure in port A to the set pressure of the pilot control valve (1) leads to the movement of the main spool (4) to the left. Pressure in port A is almost identical with the set pressure at the pilot control valve (1).
Pressure limitation
If the pressure in port A exceeds the set pressure of the pilot control valve (1), the main control spool (4) is moved further to the left.
This opens the connection from A to T and limits the pressure pending in port A to the set command value.
Type 3DREME
For hydraulic protection against an inadmissibly high electric control current at the proportional solenoid, which imperatively results in increased pressures in port A, you can optionally install a spring-loaded pressure relief valve as maximum pressure limitation (15). The maximum pressure limitation is pre-set, referred to the relevant pressure rating (see "Technical data").
