Flowserve valve positioners are advanced electro-pneumatic devices designed to ensure the precise positioning of the final control element, which is typically a valve, in response to commands from a process controller. These intelligent devices are capable of translating a standard input signal, usually within the range of 4-20 mA, into a highly accurate pneumatic output pressure needed to operate the valve effectively.
By converting the electrical signal into the required pneumatic pressure, the valve positioner helps to overcome issues such as stem friction and dynamic forces, thereby enhancing the overall control accuracy of the system. This results in improved performance and reliability, making the valve positioning process more efficient and effective in industrial applications.
Ensures precise valve positioning (< ±0.5%) for improved process control.
Supports HART, Foundation Fieldbus, and Profibus-PA protocols for seamless integration into digital control systems.
Features rugged housing (e.g., NEMA 4X / IP66) and corrosion-resistant materials for harsh environments.
Built-in monitoring of travel, pressure, and supply air provides predictive maintenance data and reduces downtime.
Simplifies setup and commissioning, reducing human error and time.
Allows for in-field selection of flow characteristics (Linear, Equal %, Quick Open).
Approved for use in explosive atmospheres (ATEX, IECEx, FM).
Optimizes plant energy usage.
