The Bosch Rexroth DBDS30K1X/220E (R900772009) is a direct operated seat valve designed for precise pressure relief in hydraulic systems. This model is a poppet seat valve with a pressure rating of up to 220 bar, ensuring reliable performance in limiting system pressure. The valve consists of a sleeve, spring, and a poppet with a damping piston that works together to maintain the desired pressure level. Users can adjust the system pressure seamlessly via an adjustment element that cannot be lost due to its gimbal mounting. The spring mechanism pushes the poppet onto the seat until the system pressure surpasses the set value, causing the poppet to open against the spring force. This allows hydraulic fluid to flow from channel P into channel T, effectively controlling excess pressure. The DBDS30K1X/220E is versatile and can be used as a screw-in cartridge valve or for threaded connections and subplate mounting. It offers various options for pressure adjustment including a sleeve with hexagon and protective cap, rotary knob, hand wheel, or lockable rotary knob depending on user preference and application requirements. Furthermore, this model ensures that even when completely unloaded, minimum pressure is maintained. If necessary, users can pull back the adjustment element to its stop for fine-tuning low pressures before screwing it back in for increased adjustments. The thoughtful design of this valve guarantees stability across its entire operational range by dividing it into specific pressure ratings corresponding to different springs. This Bosch Rexroth valve stands out for its ease of use and precision in maintaining system pressures within hydraulic applications.
