The Bosch Rexroth DB20-2-4X/350Y/12W65 (R900550273) is a high-performance pilot-operated pressure relief valve designed for regulating operating pressure within hydraulic systems. This valve ensures precise control and safety by limiting the pressure to a pre-set level. The DB20 series valve features a robust housing and an integrated pilot control valve with various adjustment types, allowing users to tailor the pressure settings to specific requirements. The operation of this valve is straightforward: the pressure in channel P influences the main spool and, once it surpasses a set value on spring, poppet opens against this spring force. This action enables hydraulic fluid from channel P to flow into the spring chamber and then be directed internally or externally to the tank, depending on the version. The equilibrium maintained at the main spool allows for a consistent flow from channel P to T, upholding the desired operating pressure. Additionally, this model includes a pressure gauge connection for monitoring system pressure and features an unloading capability via port X. It can also be switched to operate at an alternative second pressure rating when needed. Designed for subplate mounting, it adheres to ISO NG 6 and ISO NG 10 porting patterns for versatility in threaded connections. The DB20-2-4X/350Y/12W65 offers various adjustment types for setting the pressure, including options like a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or a rotary knob with scale. It supports multiple sizes and component series X with maximum operating pressures of up to 350 bar and can handle maximum flow rates as specified by its design parameters. Overall, this Bosch Rexroth valve is engineered for reliability and precision in controlling hydraulic system pressures across a range of applications.
