Brand new, genuine Flowserve 283459.999.000. Logix 3800, 3800E, 3820, and 3200MD digital valve positioner mounting kits and accessories are in stock.

Product Description:

Flowserve valve positioners are advanced electro-pneumatic devices designed to guarantee the precise positioning of the final control element, which is typically a valve. These devices play a crucial role in ensuring that the valve moves to the desired position specified by a process controller. By converting a standard input signal, such as 4-20 mA, into an exact pneumatic output pressure, they effectively trigger the valve's action. This helps overcome stem friction and other dynamic forces, ultimately leading to superior control accuracy in industrial processes.

The primary function of Flowserve valve positioners is to interpret the input signal accurately and convert it into a pneumatic output that drives the valve accordingly. By doing so, these intelligent devices facilitate smooth and precise valve movements, which are essential for maintaining optimal process performance and control. The ability to translate the input signal with precision ensures that the valve responds promptly and accurately to the commands issued by the process controller, enhancing overall operational efficiency.
