The VT-DFPE-A-21/G24K0/2A1E/V is part of the VT-DFP Directional Valves series from Bosch Rexroth and is used to route hydraulic fluid under automated control. It operates on a 24 V DC supply that tolerates +40 % to −5 % variation, so the electronics stay functional despite moderate line swings. Short-time excursions are limited between 21 V and 35 V, protecting components from deep undervoltage or brief surges. A static current draw of 0.6 A defines expected consumption during steady operation. The analog current command channel presents a 100 Ω load, giving a defined burden to a 4–20 mA source, while the analog voltage input draws from sources that can drive at least 50 kΩ without distortion. Binary control is straightforward because a digital input is recognized as high at 21 V and above and as low at 0.6 V and below, ensuring unambiguous switching by typical PLC outputs.
The valve card provides an analog monitor output that can source up to 1.5 mA, allowing supervisory hardware to read internal states without overloading the driver. Transient spool movement can require 1.25 A, establishing the upper current capacity of the integrated solenoids. Pressure capability reaches 400 bar on ports A and p for supply and work lines, whereas port T is limited to 100 bar for safe tank return. The housing is rated IP65, so dust and low-pressure water jets do not compromise the circuitry. Service temperatures may rise to 60 °C, enabling placement near warm power units, provided the hydraulic fluid remains within ISO 4406 (c) 18/16/13 cleanliness to prevent wear. A mass of 2.25 kg permits direct manifold mounting without additional support hardware.
