Section and symbol of Pressure Sequence Valve DZ 10 DP
The sequence pressure is set via the adjusting element(1).
The compression spring (2) holds the control spool (3) in the start position, the valve is closed. The pressure in port A is present at the piston area of the control spool (3) opposite to the compression spring (2) via the control line (4). When the pressure reaches the value set on compression spring (2), the control spool (3) is moved and opens the connection A to B.The system which is connected to port B is sequenced without the pressure in channel A falling.
The control signal is obtained via the control line (4) from port A or externally via connection X.
Depending on the valve application the leakage drain oil can be passed externally via connection Y or internally via B.
