Ovation 1C31194G04 Valve Positioner

Product Introduction

The Ovation 1C31194G04 Valve Positioner is a high-performance, electropneumatic device designed to deliver accurate and reliable valve control in industrial automation systems, particularly within Emerson’s Ovation™ Distributed Control System (DCS). Engineered for use in critical applications, this model is capable of interpreting analog control signals (typically 4–20 mA) and adjusting valve actuator position accordingly, ensuring smooth, efficient flow regulation in complex process environments.

As a more advanced variant in the 1C31194 series, the G04 version integrates enhanced feedback mechanisms, improved control precision, and robust build quality for harsh operating environments. With wide-ranging support for both linear and rotary actuators, the 1C31194G04 is a trusted solution for industries requiring tight control loops, diagnostics capabilities, and long operational life.

Product Specifications
