Product description
Valve type ZDZ is a direct operated pressure sequence valve in sandwich plate design. It is applied for pressure-dependent connection of a second system. The sequencing pressure is set via the adjustment type (4).
Version "C"
The compression spring (3) holds the control spool (2) in initial position, the valve is blocked. The pressure in channel A② is applied via the control line (5) at the spool face of the control spool (2) opposite the compression spring (3).
If channel A➁ reaches the set value of the compression spring (3), the control spool (2) is moved to the left and the connection from A➁ to A➀ is opened. The system connected to A➀ is connected without a pressure drop in channel A②.
The leakage oil return from the spring chamber (7) is always realized externally via channel T (Y).
A pressure gauge connection (8) enables control of the sequencing pressure at the valve.
Version "A"
Here, pressure sequencing is realized in channel A. Control signal and pilot fluid are supplied internally from channel A➀.
Version "P"
With this version, pressure sequencing is realized in channel P. Control signal and pilot fluid are supplied internally from channel P➁.
