Flowserve valve positioners are advanced electro-pneumatic devices designed to guarantee that the valve, the final control element, attains the intended position instructed by a process controller. By converting a typical input signal (such as 4-20 mA) into a precise pneumatic output pressure, these positioners activate the valve, effectively addressing stem friction and dynamic forces to ensure exceptional control precision.
With their intelligent features, Flowserve valve positioners serve critical functions in industrial processes by seamlessly transforming electrical signals into pneumatic actions. This seamless translation allows for the efficient operation of valves, enabling them to perform with high accuracy and reliability in diverse applications.
