The Bosch Rexroth DZ10-2-5X/200YM/12 (R900757266) is a sophisticated pilot-operated pressure sequence valve designed for the controlled connection of secondary systems based on pressure changes. This valve is particularly suitable for subplate mounting, with porting patterns that adhere to ISO standards. It can also be configured as a cartridge valve, offering flexibility in application.
The DZ10-2-5X/200YM/12 features a main valve with a spool insert and a pilot control valve that includes an adjustment type and an optional check valve. The functionality of this product varies based on the pilot oil supply and return, enabling differentiation between preload, sequence, and circulation valve types, each denoted by specific control line configurations.
For instance, the preload valve version allows for certain control lines to be open or closed, affecting the movement of the main spool and enabling the connection from channel A to B when the pressure set at the spring is exceeded. Similarly, sequence and circulation valves operate based on their respective configurations to manage flow paths effectively.
This model offers several adjustment types for controlling operating pressure: a rotary knob, a sleeve with hexagon and protective cap, a lockable rotary knob with scale, or a rotary knob with scale. The inclusion of an optional check valve adds to its versatility.
In terms of specifications, this particular model has a maximum operating pressure bar rating and supports maximum flow rates measured in liters per minute (l/min). Designed primarily for use as preload, sequencing, or changeover valves, it is engineered to meet precise hydraulic system requirements while ensuring reliability and performance.

The valve type DZ is a pilot-operated pressure sequence valve.
It is applied for pressure-dependent connection of a second system.
The pressure sequence valve basically consists of main valve (1) with main spool insert (7) and pilot control valve (2) with adjustment type and optional check valve (3).
According to the pilot oil supply and return and the respective function, the following differentiation is made:
Preload valve type DZ. . -.-5X/… (control lines 4.1, 12 and 13 open; control lines 4.2, 14 and 15 closed)
The pressure applied in channel A acts via the control line (4.1) on the pilot spool (5) in the pilot control valve (2). Simultaneously, the pressure in channel A acts via the nozzle (6) on the spring-loaded side of the main spool (7). If the pressure in channel P exceeds the value set at the spring (8), the pilot spool (5) is moved against the spring (8). The hydraulic fluid on the spring-loaded side of the main spool (7) now flows via the nozzle (9), the control edge (10) and control lines (11) and (12) into channel B. Due to this, a pressure drop occurs at the main spool (7). The main spool (7) is moved upwards and opens the connections from channel A to B. The pressure in channel A exceeds the value in channel B by the value set at the spring (8). The leakage occurring at the pilot spool (5) is directed internally via the spring chamber (17) of the pilot control valve and the control line (13) into channel B. If the pressure in the secondary circuit (channel B) exceeds the pressure in channel A, a check valve (3) may be optionally installed for free return flow.
Preload valve type DZ. . -.-5X/.X… (control lines 4.2, 12 and 13 open; control lines 4.1, 14 and 15 closed)
In principle, the function of this valve corresponds to the function of type DZ. . -.-5X/…. With version "X", however, the opening signal is received externally via control line X (4.2).
Sequence valve type DZ. . -.-5X/.Y… (control lines 4.1, 12 and 14 or 15 open; control lines 4.2 and 13 closed)
In principle, the function of this valve corresponds to the function of type DZ. . -.-5X/…. At version "Y", however, the leakage occurring at the pilot spool (5) has to be directed via line (14) or (15) to the tank by means of a depressurized connection. The pilot oil is directed via line (11) and (12) into channel B.
Circulation valve type DZ. . -.-5X/.XY… (control lines 4.2, 14 or 15 open; control lines 4.1, 12 and 13 closed)
In principle, the function of this valve corresponds to the function of type DZ. . -.-5X/…. With version "XY", however, the opening signal is received externally via control line X (4.2). The pilot oil at the pilot spool (16) bore and occurring leakage have to be directed via line (14) or (15) to the tank by means of a depressurized connection.
