Product Overview
The Schubert & Salzer 8049/4P5-15000-11-00 (Part No. 4056343) is a high-precision electro-pneumatic positioner engineered for demanding process control applications. Manufactured by Schubert & Salzer, a globally recognized specialist in industrial valve automation and control instrumentation, this positioner is designed to precisely regulate the stroke of pneumatic control valves by converting an electrical input signal into a proportional pneumatic output pressure. The 8049 series operates on a force-balance principle, ensuring accurate and repeatable valve positioning in response to 4–20 mA or 0–10 V control signals. This device plays a critical role in closed-loop process control systems, enabling precise modulation of flow, pressure, and temperature across a wide range of industrial processes.
