The Bosch Rexroth DZ20-3-5X/200XY (R900509821) is a highly versatile and sophisticated pilot-operated pressure sequence valve designed for the pressure-dependent connection of secondary systems. This valve is engineered to enable precise control in hydraulic circuits, where it is essential to sequence operations or prioritize one function over another. It features a main valve with a spool insert and a pilot control valve that includes an adjustable type and an optional check valve, allowing for customization to specific application requirements.
The DZ20-3-5X/200XY operates by utilizing the pressure in channel A to act on the pilot spool in the pilot control valve, while simultaneously affecting the spring-loaded side of the main spool. When the pressure in channel P surpasses the value set by the spring, it initiates movement of the pilot spool against this spring force, resulting in a shift of the main spool that opens connections from channel A to B. This action allows for controlled pressure buildup in channel A over B by a predetermined value.
The valve's design includes various versions such as preload (DZ...X), which has open control lines 1, 2, and 5; sequence (DZ...X.Y), which requires external leakage management; and circulation types (DZ...X.XY), which also require external opening signals and leakage management to tank via depressurized connections. These configurations make it suitable for preload, sequencing, and changeover applications.
For ease of integration into hydraulic systems, this model is designed for subplate mounting with porting patterns according to ISO standards. It also offers multiple adjustment types including rotary knobs and lockable rotary knobs with scales for precise settings adjustments. The optional check valve provides added functionality for free return flow when required.
With its size component series X, this Bosch Rexroth sequence valve can operate at maximum pressures up to bar units and handle flow rates up to l/min units efficiently. Its robust construction ensures reliable performance under various operational conditions making it an essential component for advanced hydraulic applications.
