The Bosch Rexroth DZ6DP1-5X/75XY (R900449212) is a high-performance direct operated pressure sequence valve designed to enable pressure-dependent connection of a secondary system. This valve is engineered for precision and reliability, allowing for the sequencing pressure to be finely adjusted. The robust construction features a compression spring that maintains the control spool in its initial position, ensuring the valve remains blocked until the desired pressure threshold is met. Once the pressure in channel P reaches the preset value of the compression spring, the control spool shifts to allow a seamless flow from P to A, activating the connected system without inducing any pressure drop in channel P. The DZ6DP1-5X/75XY facilitates both internal and external control signal reception, from channel P or via port BX respectively. Depending on its configuration, this valve can discharge leakage oil either externally through port TY or internally through A. Moreover, users should be aware that with internal leakage oil discharge, the set cracking pressure will increase proportionally to the pressure present in channel A. For applications requiring hydraulic fluid return from channel A back to channel P without resistance, an optional check valve can be integrated. To aid with monitoring and adjustments, this model includes a pressure gauge connection for direct reading of sequencing pressure at the valve itself. The DZ6DP1-5X/75XY is designed for subplate mounting and conforms to DIN form A standards without a locating hole as well as ISO standards with a locating hole. This versatile unit comes with various options for adjustment types including rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale. Users must order subplates separately as they are not included with this model. The DZ6DP1-5X/75XY boasts impressive maximum operating pressures and flow rates that cater to demanding hydraulic applications.
Valve type DZ 6 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 (4).
The compression spring (3) holds the control spool (2) in initial position, the valve is blocked. The pressure in channel P is applied via the control line (6) at the spool face of the control spool (2) opposite the compression spring (3).
If the pressure in channel P reaches the set value of the compression spring (3), the control spool (2) is moved to the left and the connection from P to A is opened. The system connected to channel A is connected without a pressure drop in channel P.
The control signal is received internally via the control line (6) from channel P or externally via port B (X).
Depending on the use of the valve, leakage oil discharge is realized externally via port T (Y) or internally via A.
Attention!
With internal leakage oil discharge, the set cracking pressure is increased by the pressure in channel A.
A check valve (5) can be optionally installed for free hydraulic fluid return flow back from channel A to channel P.
A pressure gauge connection (1) enables control of the sequencing pressure at the valve.
