The Bosch Rexroth DZ30-.-5X/... (R900503189) is a sophisticated, pilot-operated pressure sequence valve designed to facilitate the pressure-dependent connection of secondary systems. This valve is adept at managing fluid power in various applications, ensuring that a system's operations commence only after reaching a predetermined pressure level. The construction of the DZ30-.-5X/... includes a main valve with a spool insert and a pilot control valve that comes with an adjustment type and an optional check valve for versatile functionality. The operation of this valve relies on the pressure in channel A influencing the pilot spool via control line, while simultaneously exerting force on the main spool through a nozzle. When the pressure at channel P surpasses the spring-set value, it triggers movement in the pilot spool against its spring, allowing fluid to flow from channel A to B after a drop in pressure at the main spool. This model offers variations such as preload valves (DZ...X), which utilize internal control lines, and sequence valves (DZ...X.Y), where leakage is directed externally to maintain system efficiency. Additionally, circulation valves (DZ...X.XY) combine these functions by receiving external opening signals and directing leakage externally as well. The Bosch Rexroth DZ30-.-5X/... can be mounted as both a subplate and cartridge valve, adhering to ISO porting patterns. It features various pressure ratings and adjustment types including rotary knobs, sleeves with hexagons and protective caps, lockable rotary knobs with scales, or simple rotary knobs with scales for precise control over system pressures. The inclusion of an optional check valve further enhances its adaptability across different hydraulic applications. This versatility makes it suitable for use as a preload, sequencing or changeover valve in complex hydraulic systems.
