The Bosch Rexroth DR10DP1-4X/75Y (R900500257) is a direct operated pressure reducing valve, designed for subplate mounting with porting patterns in accordance with DIN Form D and ISO standards. This valve ensures the limitation of system pressure by maintaining secondary circuit pressure through an adjustable control mechanism. In its initial position, the valve allows unrestricted flow from channel B to channel A, while the secondary pressure is set via an adjustment type. The DR10DP1-4X/75Y features an open design that permits hydraulic fluid to flow freely until the set pressure threshold is reached. At this point, a control spool actuates to maintain a constant level of pressure in channel A. The internal signal and pilot oil are supplied via the control line from channel A, ensuring efficient operation. If an external force increases the pressure in channel A beyond the set point, the control spool moves against a compression spring to connect channel A with channel TY, allowing excess hydraulic fluid to discharge into the tank and preventing any significant rise in pressure. Leakage oil from the spring chamber must be discharged externally through channel TY. An optional check valve can be installed for free flow back from channel A to B. Additionally, there's a provision for a pressure gauge connection that facilitates monitoring of secondary pressure. The model offers different adjustment types including rotary knob options (with or without scale), threaded pin with hexagon and protective cap, and lockable rotary knob with scale. It is available in various sizes and component series X, capable of handling maximum operating pressures up to bar levels and maximum flow rates expressed in liters per minute (l/min). The inclusion of optional features such as a check valve enhances its versatility for various hydraulic applications.
