The Bosch Rexroth DBDS 20 K1X/315 SO481 (R900390351) is a direct operated seat valve designed for reliable pressure relief in hydraulic systems. This model ensures precise limiting of system pressure through its robust construction, which includes a sleeve, spring, poppet with damping piston for pressure ratings between 50 to 315 bar, or a ball for pressure ratings up to 630 bar. The valve operates by allowing the user to set the system pressure steplessly via an adjustment type that can be chosen from several options including a sleeve with hexagon and protective cap, rotary knob, hand wheel, or a lockable rotary knob. The DBDS 20 K1X/315 falls under the type DBDS..KX series and is characterized as a poppet seat valve suitable for various applications where precise pressure control is essential. The design ensures that the poppet or ball maintains contact with the seat until the set pressure is exceeded; at this point, it opens against the spring force to allow hydraulic fluid to flow from channel P into channel T. This process is critical in protecting hydraulic systems from excessive pressure build-up. Moreover, this model features an embossing that limits the stroke of the poppet to prevent over-travel and potential damage. For ease of maintenance and safety during operation, its adjustment element is gimbalmounted ensuring it remains movable even when completely unloaded and cannot be lost. In situations where minimum pressure does not settle despite complete unloading of the adjustment element, users can pull back the element to its stop before re-adjusting as necessary. The Bosch Rexroth DBDS 20 K1X/315 SO481 valve is versatile and can be installed as a screw-in cartridge valve or used in threaded connections and subplate mounting configurations. Its design caters to different user preferences for pressure adjustment tools while ensuring durability and reliability in controlling system pressures across various applications.
