The Bosch Rexroth ZDR6DP2-4X/75P75YM (R901302421) is a direct-operated pressure reducing valve in sandwich plate design, which is adept at maintaining the secondary circuit's pressure within set parameters. This model is specifically engineered to reduce system pressure effectively and reliably. The valve consists of a housing, control spool, compression spring, and an adjustment type to set the secondary pressure. An optional check valve can be incorporated for certain versions. The ZDR6DP2-4X/75P75YM operates by allowing hydraulic fluid to flow from channel A to A without restriction when in its initial position. The pressure is regulated through a control line which activates the piston area against the compression spring. When the system pressure exceeds the preset value, the control spool adjusts accordingly to maintain a consistent level in channel A. This model offers versatility with different versions: Version A allows for free flow back from channel A to A with an included check valve; Version P focuses on reducing pressure in channel P, with both control signal and pilot oil supplied internally; and Version B reduces pressure in channel P while extracting pilot oil from channel B. Additionally, it features a leakage oil drain from the spring chamber that must be externally connected and also provides a pressure gauge connection for monitoring secondary pressure directly at the valve. Its porting pattern adheres to ISO standards and it comes with various adjustment types such as rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or just a rotary knob with scale. This model ensures durability even in corrosive environments thanks to its corrosion-protected design.
