The pressure sequence valve type DZ 10 DP is a direct operated pressure sequence valve. It is used for pressure dependent sequencing of a second system. It is wildly sold in China and in foreign countries with high quality and lower price. Huade® pressure sequence valve fully complies with international standards in the hydraulic industry. By introducing advanced Rexroth technology, Huade® hydraulic valves are compatible with Rexroth in performance.

Application:
This pressure sequence valve DZ 10 DP can be widely used in hydraulic systems of lifting and transport machinery, construction machinery, industrial vehicles, machine tools, ships, metallurgy and other equipment.
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.
