The Siemens 73N12F valve positioner is a compact, advanced instrument designed for precise and stable control valve positioning. Its top-loading design simplifies installation and integration, while the direct acting mechanism ensures immediate and responsive valve control. The positioner operates on a single-axis, force-balance principle, guaranteeing reliable and stable valve positioning. With the capability to support input spans ranging from 2 to 12 psi, it caters to various control needs. Feedback circuits continuously monitor and adjust the actuator’s position to match the control instrument signal. Additionally, the versatile range spring selection offers a broad selection of springs to accommodate different valve strokes from 1/4″ to 4″ and instrument spans from 2 to 24 psi. Mounted directly on the valve’s topwork without the need for external levers or exposed mechanisms, the Siemens 73N12F valve positioner delivers exceptional performance and flexibility for a wide range of valve control applications.
