The Bosch Rexroth DBDS20K1X/170E (R900774523) is a direct operated seat valve designed for pressure relief applications. This model is a part of the DBD series, which are utilized to limit system pressure effectively. The valve comprises essential components such as a sleeve, spring, poppet with damping piston for pressure ratings up to 315 bar, or a ball for pressure ratings up to 400 bar. The adjustable feature of this valve allows for precise system pressure settings that can be altered steplessly. The DBDS20K1X/170E operates by the spring forcing the poppet or ball onto its seat while channel P is connected to the system's pressure. When this pressure surpasses the preset level on the spring, the poppet or ball lifts against the spring force, allowing hydraulic fluid to flow from channel P into channel T. To prevent overextension, the poppet stroke is confined by an embossing on the valve. To cater to various operational requirements, Bosch Rexroth has divided the entire pressure range into different ratings, each corresponding to a specific spring that determines maximum operating pressures achievable with that spring. The DBDS..KX version is a poppet seat valve suitable for pressure ratings up to 315 bar. For user convenience and safety, this model features an adjustment type designed to prevent loss and allow loose movement within its housing even when completely unloaded. If minimum pressure does not stabilize despite an unloaded adjustment type, users can retract and then screw in the adjustment element again for increased pressure adjustment. The DBDS20K1X/170E offers various options for adjusting pressure: a sleeve with hexagon and protective cap, rotary knob, hand wheel, or lockable rotary knob. This versatility ensures that it can be tailored to specific application needs whether it's installed as a screw-in cartridge valve or intended for threaded connections or subplate mounting.
