The Bosch Rexroth DZC2-5X/200/12 (R900563201) is a sophisticated, pilot-operated pressure sequence valve designed for the pressure-dependent connection of secondary systems. This valve is particularly adept at managing the flow of hydraulic fluid in a controlled sequence, ensuring that the pressure in one channel reaches a set value before allowing fluid to pass to another part of the system. The main components include a main valve with spool insert and a pilot control valve which comes with various adjustment types and an optional check valve. The DZC2-5X/200/12 operates by responding to pressure changes in channel A, which acts on the pilot spool within the pilot control valve. As the pressure in channel P surpasses a predetermined spring setting, it shifts the pilot spool against this spring force, allowing hydraulic fluid to flow into channel B and causing a drop in pressure at the main spool. This action prompts the main spool to move and create a pathway from channel A to B. This model can function as a preload valve, sequence valve, or circulation valve depending on its configuration, with different versions (X, X.X, X.Y, X.XY) indicating how control lines are managed and whether leakage is internally directed or needs to be routed externally. The DZC2-5X/200/12 is suited for subplate mounting and conforms to ISO porting patterns. It offers various adjustment types including rotary knobs (with or without scale), sleeves with hexagon and protective cap, as well as lockable rotary knobs with scale. An optional check valve can be included for applications requiring free return flow when the secondary circuit's pressure exceeds that of channel A. In terms of specifications for this model: it belongs to component series X; can handle maximum operating pressures up to bar; and is capable of accommodating maximum flow rates measured in liters per minute. Overall, this Bosch Rexroth pressure sequence valve stands out for its versatility and precision control in hydraulic systems where sequential operations are critical.
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.
