The Bosch Rexroth DR10DP2-4X/210Y (R900594125) is a high-performance direct operated pressure reducing valve designed for subplate mounting with a porting pattern according to DIN Form D and ISO standards. This valve is part of the component series X, which is distinguished by its robust construction and capability to handle maximum operating pressures up to 210 bar, with a maximum flow rate of liters per minute. The DR10DP2-4X/210Y functions by limiting system pressure through its way version design, providing pressure limitation of the secondary circuit. The secondary pressure is adjustable via the chosen adjustment type, such as a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, or a rotary knob with scale. The valve's initial open position allows hydraulic fluid to flow freely from channel B to channel A without restrictions. Pressure control is achieved through the interaction between the compression spring and control spool. When pressure in channel A surpasses the set value on the compression spring, the control spool moves into position to maintain a constant level of set pressure in channel A. Additionally, signal and pilot oil are internally supplied via the control line from channel A. External forces acting on the actuator that increase pressure in channel A result in further movement of the control spool against the compression spring. This action connects channel A to channel TY through the control edge on the control spool, allowing excess hydraulic fluid to discharge into the tank and maintaining slight pressure increases. Leakage oil from the spring chamber is discharged externally via channel TY. For reverse flow from channel A back to channel B without restrictions, an optional check valve can be installed. Moreover, this valve features a pressure gauge connection for monitoring secondary pressure levels effectively. In summary, Bosch Rexroth's DR10DP2-4X/210Y offers precise secondary circuit pressure limitation capabilities suitable for various hydraulic applications requiring reliable and consistent performance under high-pressure conditions.
