The Bosch Rexroth DR6DP3-5X/75Y (R900469279) is a direct operated pressure reducing valve designed to manage and limit system pressure within hydraulic applications. The valve operates by allowing hydraulic fluid to flow from channel P to channel A without restriction when in the initial position, while simultaneously applying pressure from channel A to the piston area opposite the compression spring through a control line. As the pressure in channel A exceeds the value set by the compression spring, the control spool adjusts to maintain a constant level of set pressure. This model features internal signal and pilot oil delivery via the control line from channel A, ensuring that any external force increasing pressure in channel A causes further movement of the control spool against the spring, thereby connecting channel A to channel TY through a control edge on the spool. This connection allows excess hydraulic fluid to be discharged into the tank, preventing significant pressure increases. The DR6DP3-5X/75Y is designed for subplate mounting with porting patterns that conform to DIN form A and ISO standards with an optional locating hole. It offers various adjustment types including a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale. Additionally, it may include an optional check valve for free flow back from channel A to channel P. The model also includes a pressure gauge connection for monitoring secondary pressure. It comes in different sizes and component series X, capable of handling maximum operating pressures up to certain bar levels and maximum flow rates measured in liters per minute. The external leakage oil discharge from the spring chamber is always directed via channel TY. This valve's precise construction ensures reliable performance in controlling system pressures across diverse hydraulic applications.
