The Bosch Rexroth ZDR6DP7-4X210YMV/12 (R978008323) is a direct operated pressure reducing valve designed for efficient control of system pressure. This sandwich plate valve is engineered to reduce the system pressure by limiting the secondary circuit's pressure. It incorporates a robust housing, a control spool, and a compression spring for reliable operation. The secondary pressure can be precisely set via an adjustment mechanism. This model features Version A, which allows hydraulic fluid to flow unrestricted from channel A to channel A when in its initial open position. The pressure in channel A is regulated through the control line acting on the piston area against the compression spring. When external forces cause an increase in channel A's pressure, the control spool shifts against the spring, connecting channel A to the tank and maintaining constant pressure by discharging excess hydraulic fluid. The valve includes a leakage oil drain from the spring chamber that must be externally connected via bore and channel TY. Additionally, it provides a pressure gauge connection for monitoring secondary pressure directly at the valve. Version A also supports a check valve enabling free flow back from channel A to A. Other versions such as P and B cater to different requirements; with P focusing on reducing pressure in channel P and B reducing it in P but drawing pilot oil from B. It's crucial to note that if using a directional valve with spool position P to A, the pressure in channel B should not surpass the set secondary pressure. The ZDR6DP7-4X210YMV/12 offers various adjustment types including rotary knob options, both lockable and with scale, as well as sleeve with hexagon and protective cap configurations. It supports maximum operating pressures and flow rates specific to its size and series designation. The design also includes corrosion protection features for enhanced durability. This particular model adheres to ISO porting patterns, providing versatility for different system requirements.
