Product Overview
The Schubert & Salzer 8049/4P5-1S000-11-00 is a high-precision electro-pneumatic positioner engineered for reliable control of pneumatic control valves in demanding industrial process environments. As a member of the Schubert & Salzer 8049 series, this unit converts a standard electrical control signal into a proportional pneumatic output pressure, enabling accurate valve stem positioning and precise process regulation. The positioner operates on a force-balance feedback principle, continuously comparing the input signal against the actual valve position and adjusting the pneumatic output to eliminate deviation. This model is configured for single-acting spring-return actuators and is widely deployed in flow, pressure, temperature, and level control loops where repeatability and fast dynamic response are essential.
