VT-VRPA1-537-11/V0/PV by Bosch Rexroth Indramat

The Bosch Rexroth Indramat VT-VRPA1-537-11/V0/PV electric amplifier from the VT-VRPA Electric Amplifiers series provides precision throttle valve control for industrial automation applications. This robust device features an integrated plug-in connection style and a compact PCB format measuring Dimensions 150 x 100 x 75 mm, allowing for straightforward PCB mounting and service. The amplifier delivers a Flow Coefficient (cv) of 12.5 and supports a Pressure Rating of PN16 for high-performance fluid control when paired with compatible Electric Actuators. Housings are constructed of Material Stainless Steel to withstand demanding environments, and the unit weighs 5.2 kg for optimized system balance. Reverse polarity protection and onboard jumpers for valve type adjustment ensure reliable operation and rapid configuration in the field.

Technical specifications are comprehensive and engineered for precision. The unit offers Actuator Compatibility Electric Actuator interfaces, coupled with a Sealing Type PTFE Lined design for leak-free performance. Mounting flexibility is provided by a Mounting Orientation Horizontal/Vertical option and robust End Connection Flanged hardware. The amplifier handles an Operating Torque of 20 Nm in high-load situations while meeting Standards Compliance ISO 9001 quality requirements. The operational Temperature Range of -20°C to 120°C ensures consistent performance in extreme thermal environments.

Operational features focus on fine-tuning and feedback. A differential setpoint input signal supports precise command value control, and potentiometers allow incremental adjustment of flow response characteristics. Onboard LEDs (green, yellow, red) deliver visual status feedback for power, command, and fault conditions. The integrated ramp generator converts stepped inputs into smooth output profiles, and an oscillator with downstream driver circuitry optimizes position transducer electronics. Jumper-configurable settings permit quick adaptation for various valve sizes, including support for both FE and FES ball valves, enhancing versatility.

System integration is streamlined for industrial automation and throttle valve control networks. The amplifier’s plug-in connection style and jumper adjustments simplify installation into existing control cabinets. Its stainless steel construction and PTFE sealing make it suitable for both horizontal and vertical assemblies in packaging, process control, and mobile hydraulic systems. The combination of high flow precision, reliability, and Bosch Rexroth Indramat quality positions the VT-VRPA1-537-11/V0/PV as an ideal solution for OEMs and system integrators seeking robust electric valve actuation.
