Function, section

The 3-way pressure reducing valve type 3 DREP 6.. is direct operated by proportional solenoids. It is used to convert an electric input signal into a proportional pressure output signal.

The proportional solenoids are controllable wet-pin DC solenoids with central thread and detachable coil. The solenoids are optionally actuated by external control electronics(type 3DREP) or by the internal control electronics(type 3DREPE).

Set-up:

The valve basically consists of:

– Housing (1) with connection surface

– Control spool (2) with pressure measuring spool (3, 4)

– Solenoids (5, 6) with central thread

– Optionally integrated control electronics (7)

Function:

The pressure in A or B is set by means of the proportional solenoids. The amount of the pressure depends on the current.

With de-energized solenoids (5, 6), the control spool (2) is held in the central position by means of the pressure springs (8). Ports A and B are connected with T so that the hydraulic fluid can flow off to the tank without obstructions.
