The Bosch Rexroth DZ10DP1-4X/75XYM (R978868995) is a high-performance direct operated pressure sequence valve designed for controlling the sequence of hydraulic systems by pressure-dependent connection of a second system. This valve facilitates precise control, as the sequencing pressure is adjustable through various methods such as a rotary knob, threaded pin with hexagon and protective cap, lockable rotary knob with scale, and a rotary knob with scale. The DZ10DP1-4X/75XYM model features an integrated compression spring that maintains the control spool in its initial position, ensuring that the valve remains blocked until the set pressure threshold is reached. Upon reaching this set value in channel A, the control spool shifts to permit flow from A to B without causing a drop in channel A's pressure. The system attached to channel B thus operates seamlessly. The design allows for either internal or external reception of the control signal through port X and manages leakage oil discharge via port Y or internally through channel B. It's important to note that internal leakage oil discharge will affect the set cracking pressure due to additional pressure in channel B. For enhanced functionality, an optional check valve can be installed allowing free return flow of hydraulic fluid from channel B to channel A. Additionally, monitoring and maintenance are made more accessible with a pressure gauge connection that checks sequencing pressure directly at the valve. The DZ10DP1-4X/75XYM is engineered for subplate mounting and adheres to ISO standard porting patterns. It boasts impressive operating parameters with a maximum operating pressure of up to 350 bar and a maximum flow rate capacity of 75 liters per minute (l/min), making it suitable for various heavy-duty applications where reliable sequencing is critical.
