Product Introduction
The Ovation 1C31197G03 Valve Positioner is a high-performance electropneumatic device developed by Emerson Process Management for precise and reliable valve actuation in complex process control environments. Part of the broader Ovation™ Distributed Control System (DCS) platform, this positioner translates control signals into exact mechanical valve positions, ensuring optimal performance of linear or rotary actuators.
Designed for critical industrial sectors like power generation, petrochemicals, and water treatment, the 1C31197G03 ensures accurate control over process variables such as flow, pressure, and temperature. It supports analog 4–20 mA control signals and features feedback capabilities for system diagnostics and monitoring. The unit is ideal for installations requiring both responsiveness and robustness, especially in environments exposed to dust, moisture, and temperature extremes.
