The Bosch Rexroth DB20G2-4X/315W65 (R900423704) is a high-quality pressure relief valve designed for controlling operating pressure within hydraulic systems. This pilot-operated valve is integral in limiting the system's operating pressure by utilizing a housing and a pilot control valve with an adjustment mechanism. The main spool of the valve responds to pressure changes in channel P, with the applied pressure simultaneously acting on a poppet through nozzle bores. When the pressure exceeds a preset value, the poppet opens against its spring, allowing hydraulic fluid to flow into the spring chamber and subsequently into the tank—either internally or externally, depending on the version. This model features various adjustment types for precise pressure settings, including options such as a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale. The versatility in adjustment types ensures adaptability for different user preferences and applications. Designed for subplate mounting, the DB20G2-4X/315W65 adheres to ISO standards NG6 and NG10 for porting patterns. It is also equipped with a port X that allows for unloading or switching to an alternative pressure setting when necessary. A notable feature of this valve is its integrated pressure gauge connection which facilitates monitoring of the operating pressure to ensure system reliability. The Bosch Rexroth DB20G2-4X/315W65 is suitable for various hydraulic applications where maintaining a specific operating pressure is crucial for performance and safety. Its robust design and precision engineering make it an essential component in advanced hydraulic systems requiring dependable pressure relief functionality.
