The VT-DFPE-A-22/G24K0/2A0F/V valve control card belongs to the VT-DFP Directional Valves series and is manufactured by Bosch Rexroth for hydraulic automation. It translates electrical commands into solenoid current for spool positioning inside proportional directional valves. The module runs from a 24 VDC supply so it can share the standard power rail in machine cabinets. Operation continues during brief dips down to 21 VDC because the short-time lower voltage is set at that level, and it withstands surges up to 35 VDC for noise immunity. Continuous draw is held to 0.6 A, while a 1.25 A maximum accommodates spool acceleration demands. Digital inputs register a logic-high at 21 V, allowing direct PLC interfacing. The analog voltage input presents at least 50 kΩ of load to reduce source burden, and the analog current input uses a 100 Ω burden resistor for predictable 4–20 mA scaling. Total mass is 2.25 kg, making the unit light enough for manifold or panel mounting.
The card provides two analog monitor outputs that each supply no more than 1.5 mA, ensuring external indicators or controllers cannot overload the drivers. Hydraulic oil supplied to the connected valve must meet ISO 4406 cleanliness level 18/16/13 to minimize wear on precision edges. Pressure capability reaches 400 bar at ports A and P so the assembly can handle high-force actuators, while port T is limited to 100 bar for controlled tank back-pressure. FKM sealing elements are fitted to resist common hydraulic fluids and elevated temperatures encountered in industrial service. An IP65 enclosure rating blocks dust and low-pressure water jets, enabling installation on open machinery without additional covers. Together these ratings, signal limits, and pressure boundaries define the operating envelope required for reliable spool control in proportional directional valve circuits.
