Function, section The valve type ZDZ is a direct operated pressure sequence valve in sandwich plate design. It is used for the pressuredependent sequencing of a second system. The sequencing pressure is set via the adjustment type (4).

The leakage oil drain from the spring chamber (7) is always realized externally, via channel T (Y).

Version “C”

Version “A”

A pressure gauge connection (8) allows for the control of the sequencing pressure at the valve.

The compression spring (3) holds the control spool (2) in the initial position - the valve is blocked. Via the pilot line (5), the pressure in channel A② is applied to the spool face of the control spool (2) vis-à-vis the compression spring (3).

Here, the pressure is sequenced in channel A. Control signal and pilot fluid are provided internally, from channel A①. Version “P”

If the pressure in channel A② reaches the set value of the compression spring (3), the control spool (2) is pushed to the left and the connection A② to A① is opened. The system connected at A① is sequenced without a drop of the pressure in channel A②.

With this version, the pressure is sequenced in channel P. Control signal and pilot fluid are provided internally, from channel P②.
