Function, section
The valve type DZ 6 DP is a direct operated pressure sequence valve.
It is used for the pressure dependent connection of a second system.
The setting of the sequence pressure is via the adjusting element(4).
The spring (3) holds the control spool (2) in the neutral position, the valve is blocked. The pressure in channel P is present at the spool surface of the control spool (2) opposite the spring (3) via the control line (6).
If the pressure in channel P reaches the set value of the spring (3) the control spool (2) is moved to the left and the connection
P to A is opened. The system at channel A is connected without a pressure decrease falling in diannel P. The control signal originates internally via the control line (6) from channel P or externally via port B (X).
Depending on the use of the valve the leakage oil drain is externally via port T (Y) or internally via A.
