The Bosch Rexroth DR6DP7-5X/75YM/12 (R900935344) is a direct operated pressure reducing valve designed for subplate mounting with a porting pattern that complies with DIN form A and ISO standards, featuring an optional locating hole. This model is part of the DR DP valve series, which specializes in controlling system pressure by limiting the secondary circuit. It operates by allowing hydraulic fluid to flow freely from channel P to channel A when in the initial position, while the secondary pressure is adjusted through a specific adjustment type. The valve maintains constant pressure in channel A through its control spool mechanism, which reacts to pressure changes and adjusts accordingly to keep the set pressure level stable. The internal signal and pilot oil are sourced from channel A via a control line, ensuring efficient operation even when external forces affect the actuator. In case of increased pressure in channel A beyond the set value, the control spool shifts further against the compression spring, allowing excess hydraulic fluid to be discharged into the tank through channel TY. This process prevents significant pressure rises. The model also includes an external leakage oil discharge via channel TY from the spring chamber. For reverse flow from channel A back to channel P, there's an option to install a check valve. Monitoring of secondary pressure is facilitated by a pressure gauge connection provided on the valve. The DR6DP7-5X/75YM/12 offers various adjustment types including a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale for precise control. It supports different pressure ratings and has maximum operating pressures of up to 315 bar with maximum flow rates reaching 40 l/min. This particular model ensures robust performance for hydraulic systems requiring precise secondary pressure regulation.
