For subplate mounting Porting pattern according to ISO 5781 For threaded connection As cartridge valve 4 optional adjustment types:• Rotary knob• Sleeve with hexagon and protective cap• Lockable rotary knob with scale• Rotary knob with scale 5 pressure ratings Check valve, optional (subplate mounting only)

Pressure valves type DR are pilot-operated pressure reducing valves controlled from the secondary circuit.

The pressure reducing valves basically consist of the main valve (1) with main spool insert (3) and pilot control valve (2) with pressure adjustment element.

Basic principle:

In rest position, the valves are open. Hydraulic fluid can flow via the main spool insert (3) from channel B to channel A without restrictions. The pressure applied in channel A acts on the bottom of the main spool. Simultaneously, pressure is applied via the nozzle (4) to the spring-loaded side of the main spool (3) and via channel (5) to ball (6) in the pilot control valve (2). Similarly, it acts via nozzle (7), control line (8), check valve (9) and nozzle (10) on the ball (6). Depending on the setting of the spring (11), pressure builds up upstream of the ball (6), in channel (5) and in the spring chamber (12) holding the control spool (13) in open position. The hydraulic fluid in channel B can flow via the main spool insert (3) to channel A without restrictions until a pressure builds up in channel A exceeding the value set at the spring (11) and opening the ball (6). The control spool (13) is moved into closing direction.

The desired reduced pressure is reached if there is a balance between the pressure in channel A and the pressure set at the spring (11).

The pilot oil return from the spring chamber (14) is always realized externally via the control line (15) into the tank.

For the free return flow from channel A to channel B, a check valve (16) can optionally be installed.

A pressure gauge connection (17) enables control of the reduced pressure in channel A.
