The Bosch Rexroth DBT2-5X/200/12 (R901192048) is a sophisticated pressure relief valve designed to regulate operating pressure within hydraulic systems. This pilot-operated valve ensures the stability and safety of the system by limiting the pressure to a pre-set level. The valve's construction includes a main valve with a spool insert and a pilot control valve that features a pressure adjustment element, allowing for precise control over system pressure. The DBT2-5X/200/12 operates by balancing the pressure applied to channel P against the force of an adjustment spring. When system pressure surpasses the spring's threshold, it opens a ball in the pilot control valve, allowing fluid to flow from channel P through control lines and nozzles into the tank—either internally or externally, depending on the type. This action maintains consistent operating pressure by creating a drop at the main spool, triggering the connection from channel P to T. This model is versatile in its mounting options, supporting subplate mounting with porting patterns according to ISO standards NG6, NG10, and NG16 for easy integration into various hydraulic systems. It can also be installed as a screw-in cartridge valve for threaded connections. Users have several adjustment types for setting pressure: rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale—providing flexibility based on user preference or application requirements. Additionally, this model offers different pressure ratings and features a corrosion-protected design that ensures durability even in harsh working environments. The DBT2-5X/200/12 also includes an unloading feature via port X and can switch to an alternative second pressure rating if needed for complex hydraulic circuits or applications requiring variable pressures.
