The Bosch Rexroth DZ 6 DP1-5X/210XYM/12 (R978020063) is a high-performance direct operated pressure sequence valve designed to enable pressure-dependent connection of a secondary system. This valve operates by utilizing a compression spring that holds the control spool in its initial position, effectively blocking the valve. The pressure in channel P is applied to the spool face opposite this spring. Once the pressure reaches the set value of the spring, the spool moves, allowing flow from P to A and connecting the system to channel A without causing a drop in channel P's pressure. The DZ 6 DP1-5X/210XYM/12 model receives its control signal either internally from channel P or externally through port BX. Depending on how this valve is utilized, leakage oil discharge can be managed externally via port TY or internally through A. Notably, if internal leakage oil discharge is selected, this will result in an increase in the set cracking pressure due to pressure within channel A. This model also allows for an optional check valve installation for unimpeded hydraulic fluid return from channel A to P. Additionally, a pressure gauge connection provides an opportunity for monitoring sequencing pressure directly at the valve. The DZ 6 DP1-5X/210XYM/12 comes with several options for subplate mounting, including porting patterns that adhere to DIN form A standards without locating holes or ISO patterns with locating holes. Subplates are available as separate orders. The maximum operating pressures and flow rates are delineated by size and component series marks, ensuring compatibility across various applications. Adjustment types for this model are diverse and include options such as a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale—each catering to different user preferences and requirements for precision control. The inclusion of an optional check valve enhances versatility in hydraulic circuit design.
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.
