Product Overview
The Rexroth DBDS 6 K1X/100 (Material No. R900423723) is a direct operated pressure relief valve from the proven DBDS series, engineered by Bosch Rexroth for precise system pressure limitation and protection in industrial hydraulic circuits. As a direct acting poppet-type valve, it responds instantaneously to pressure surges without pilot-stage lag, making it ideal for safeguarding pumps, accumulators, and downstream components against overpressure. The valve is designed for subplate mounting in accordance with ISO 6264 (size 6), and its K1X pressure adjustment element allows stepless setting of the cracking pressure up to 100 bar. This model serves as a reliable, tamper-resistant safety and pressure-limiting element in demanding stationary and mobile hydraulic power units.
