Function, section
Pressure valves of 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 adjustment type.
In the rest position the valves are open. Hydraulic fluid flows from channel B via the main spool insert (3) to channel A without restrictions. The pressure applied to channel A acts on the lower main spool side. At the same time, pressure is applied to the spring-loaded side of the main spool (3) via the nozzle (4) and to the ball (6) in the pilot control valve (2) via the channel (5). It also acts via the nozzle (7), control line (8), check valve (9) and nozzle (10) on the ball (6). Depending on the setting of the spring (11), a pressure builds up in front of the ball (6), in the channel (5) and in the spring chamber (12) holding the control spool (13) in the opened 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 which exceeds the value set at the spring (11) and opens the ball (6). The control spool (13) moves into closing direction.
The desired reduced pressure is achieved when there is a state of equilibrium 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 flow back from channel A to channel B, a check valve (16) can optionally be installed.A pressure gauge connection (17) allows for the control of the reduced pressure in channel A.
