The Bosch Rexroth DZ10-1-5X/315XV/12 (R978016089) is a sophisticated pilot-operated pressure sequence valve designed for the pressure-dependent connection of secondary systems. This high-performance valve features a main spool insert and a pilot control valve, which includes an adjustment type and an optional check valve for versatile application. The DZ10-1-5X/315XV/12 operates by allowing the pressure in channel A to act on the pilot spool in the pilot control valve, while also impacting the spring-loaded side of the main spool. When the pressure at channel P surpasses a predetermined value, set by an adjustable spring, it triggers movement in the pilot spool against this spring force.
This action permits hydraulic fluid to flow from the spring-loaded side of the main spool through various nozzles and control lines into channel B, prompting a pressure drop at the main spool and thereby connecting channels A to B. Additionally, any leakage from the pilot spool is internally redirected into channel B, ensuring efficient operation. For scenarios where pressure in channel B exceeds that of channel A, an optional check valve can be installed to facilitate free return flow.
The DZ10-1-5X/315XV/12 can serve as a preload valve, sequence valve or circulation valve depending on its configuration and control line connections. It is suitable for subplate mounting with porting patterns conforming to ISO standards and can also be utilized as a cartridge valve. The unit offers various adjustment types including rotary knobs (with or without scales), sleeves with hexagon and protective cap, or lockable rotary knobs with scale. This versatility ensures that it meets diverse application requirements across different systems.
With a maximum operating pressure of 315 bar and maximum flow rate specifications available upon order placement, this Bosch Rexroth sequence valve is equipped to handle demanding hydraulic applications while offering precise control over system pressures and sequences.

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.
