Product description
Valve type DZ 10 DP is a direct operated pressure sequence valve. It is applied for pressure-dependent connection of a second system. The sequencing pressure is set via the adjustment type (1).
The compression spring (2) holds the control spool (3) in initial position, the valve is blocked. The pressure in channel A is applied via the control line (4) at the spool face of the control spool (3) opposite the compression spring (2).
If the pressure in channel A reaches the set value of the compression spring (2), the control spool (3) is moved to the right and the connection from A to B is opened. The system connected to channel B is connected without a pressure drop in channel A.
The control signal is received internally via the control line (4) from channel A or externally via port X.
Depending on the use of the valve, leakage oil discharge is realized externally via port Y or internally via B.
Attention!
With internal leakage oil discharge, the set cracking pressure is increased by the pressure in channel B.
A check valve (5) can be optionally installed for free hydraulic fluid return flow from channel B to channel A.
A pressure gauge connection (6) enables control of the sequencing pressure at the valve.
