The Bosch Rexroth DZ20-1-5X/200XYM (R900501371) is a sophisticated, pilot-operated pressure sequence valve designed for the pressure-dependent connection of secondary systems. This hydraulic component ensures precise control by allowing connections from one channel to another once a set pressure threshold is surpassed. The main valve consists of a main spool insert and a pilot control valve that includes an adjustment type and an optional check valve for versatile application. This model can function as a preload valve, with specific control lines being open or closed to regulate the flow based on the applied pressure in channel A, which acts on the pilot spool in the pilot control valve. As the pressure in channel P exceeds the set value on the spring, it activates the main spool, enabling fluid flow from channel A to B. An optional check valve can be installed for free return flow if required. The variant DZ20-1-5X/200XYM also serves as a sequence and circulation valve, where its function can be externally signaled via a control line for opening. In cases where leakage occurs at the pilot spool, it is directed to the tank through a depressurized connection ensuring efficient operation and system safety. This model is suitable for subplate mounting and conforms to ISO porting patterns. It offers various pressure ratings and adjustment types including rotary knobs (with or without scales), sleeves with hexagon and protective cap, or lockable rotary knobs with scale for precise adjustments. The addition of an optional check valve further enhances its application flexibility. Its robust design makes it ideal for use in complex hydraulic systems requiring reliable sequencing or changeover functions.
