Rexroth VT-VSPD-1 RE30123 Digital Proportional Valve Amplifier

Product Description

VT-VSPD-1 (Doc. No. RE30123) is a digital proportional valve amplifier from Bosch Rexroth, designed in Euro-card format. It drives and controls hydraulic proportional valves, supporting single-solenoid and double-solenoid proportional valves. Parameter setting, calibration and fault diagnosis are realized via BODAC software. Featuring high precision, stable signal and strong anti-interference performance, it is commonly matched with Rexroth DRE, ZDRE proportional pressure reducing valves and flow valves, serving as the core electronic control card for hydraulic closed-loop control systems.
