Product Description

Rexroth R900537344 VT11131-1X/

The Rexroth R900537344 VT11131-1X/ is an analog amplifier module specifically designed for controlling direct operated proportional pressure valves that operate without electrical position feedback. This Eurocard format amplifier provides precise and stable control signals, enabling accurate pressure regulation in various hydraulic applications. It features adjustable parameters for zero point, gain, ramp times, and maximum value, allowing for fine-tuning to specific system requirements.
