Product Overview
The Schubert & Salzer 8049/4P5-1S000-11-00 (part number 4058343) is a high-precision electro-pneumatic positioner engineered for the accurate control and positioning of pneumatic control valves and quarter-turn actuators within demanding industrial process loops. Operating on a force-balance feedback principle, the unit converts a standard electrical control signal into a proportional pneumatic output pressure, driving the actuator stem or rotary shaft to a position that precisely matches the commanded setpoint. As a core component of the Schubert & Salzer 8049 series, this positioner delivers the fast dynamic response, tight positioning accuracy, and long-term stability required for continuous modulating service in chemical, petrochemical, and general process industries.

Engineering Features & Advantages
- Precision Performance: Force-balance feedback mechanism delivers accurate, repeatable valve positioning with minimal dead band, ensuring tight process control across the full stroke or rotation range.
- Fast Dynamic Response: High-gain pneumatic pilot stage provides rapid response to setpoint changes, minimizing process deviation in modulating control loops.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction that resists vibration, temperature variation, and contaminated instrument air.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM Schubert & Salzer 8049 series standards, allowing drop-in replacement without actuator modification.
Typical Industrial Applications
This electro-pneumatic positioner is widely deployed in chemical and petrochemical processing plants for precise control of control valves on flow, pressure, and temperature loops; in power generation stations for steam and feedwater valve regulation; in water and wastewater treatment facilities for modulating butterfly and globe valves; and in general process industries such as pulp and paper, food processing, and pharmaceutical manufacturing where accurate pneumatic valve positioning is essential for product quality and process safety.
