***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth VT-DFPC-A-2X/G24K0/2A0V/V (R901029309) is a sophisticated pilot valve designed for precision pressure and flow control within hydraulic systems. This model operates through a proportional solenoid which benefits from electrical feedback, ensuring highly accurate and responsive control. The valve is particularly suited to integrate with the SYHDFE pressure and flow control system, providing seamless operation within complex hydraulic circuits. The VT-DFPC model comes equipped with control electronics, specifically the VTDFPC for SYHDFEC, which are integrated and digital with a CANBus interface. This advanced feature allows for direct digital communication within automated systems, enhancing the valve's functionality in terms of monitoring and adjusting parameters in real-time. Capable of handling a maximum operating pressure, this valve stands out for its robust performance in demanding applications. Its design is engineered to offer reliability and precision, making it an essential component for systems that require consistent flow and pressure regulation. In summary, the Bosch Rexroth VT-DFPC-A-2X/G24K0/2A0V/V is an integral part of modern hydraulic systems that demand high levels of control accuracy and integration capability with digital communication interfaces. Its compatibility with the SYHDFE system underscores its role as a critical component in advanced fluid power applications.

1) Connector dependent on the valve type (see "Technical data" and "Electrical connection”).
2) With the SY(H)DFEn control system with analog interfaces, the plug-in connector X2 can not be used as actual pressure value input. Thus, a separate pressure transducer has to be used and connected to plug-in connector X1 in this case.
3) Only in connection with SYHDFE and spool design C (feature 2).
