Pressure Sequence Valve DZ 5 DP

Huafilter specializes in supplying Huade® pressure sequence valve DZ 5 DP. Established through a strategic partnership between the Chinese and German governments in 1979, Huade Hydraulic has incorporated cutting-edge technology from Rexroth. Huade® pressure sequence valve has come up to the international standards. They are competitive with well-know products with good quality and lower price. As the authorized distributor of Huade Hydraulic, we aim to provide customers with high-quality and low-cost products. We have experienced engineers who can provide timely technical support.

Pressure Sequence Valve DZ 5 DP are used to direct oil to a second system at a set pressure.

Due to the introduction of Rexroth's advanced technology, Huade® hydraulic valves are compatible with Rexroth in performance and quality. The price is more reasonable. The factory has advanced production equipment and strict testing systems from all over the world to ensure the superior performance of the products.

1. Section and symbol of Pressure Sequence Valve DZ 5 DP

Valves type DZ 5 DP are direct operated sequence valves. Valves of this type consist basically of the housing (1), control spool (2), springs (3) and pressure setting element (4), and additionally non-return valve (5) if required.

The pressure at which the valve passes oil is set at the pressure setting element (4).The springs (3) hold the control spool(2) in the starting position, and the valve remains closed. The pressure in port P passes via drilling (6) and jet (7) on to the spool operating area at the opposite end to the control springs (3).


When pressure in port P reaches the set value, the spool moves against the spring to connect port P to port A.

The signal for this passes internally via drilling (6) from port P.

Oil now passes to the system connected to port A, but the pressure in port P does not fall.

The pilot oil may also be fed externally via port B(X).

Depending on the application of the valve, the pilot oil return may be externally via port T(Y) or internally.

In order to allow free return flow of the oil from port A to port P, non-return valve(5) may be included if required.
