Product Description:
Flowserve valve positioners are sophisticated electro-pneumatic
devices designed to ensure precise positioning of the final control
element, which is typically a valve. These intelligent devices play
a crucial role in responding to commands from a process controller
and translating them into actions that result in the valve reaching
the desired position.
By converting a standard input signal, such as 4-20 mA, into an
accurate pneumatic output pressure, the valve positioner
effectively activates the valve. This process enables the valve to
overcome challenges such as stem friction and dynamic forces,
thereby enhancing control accuracy and performance.
Features:
High Accuracy & Repeatability: Ensures precise valve positioning (< ±0.5%) for improved
process control.
Advanced Digital Communication: Supports HART, Foundation Fieldbus, and Profibus-PA protocols for
seamless integration into digital control systems.
Robust Construction: Features rugged housing (e.g., NEMA 4X / IP66) and
corrosion-resistant materials for harsh environments.
Intuitive Diagnostics: Built-in monitoring of travel, pressure, and supply air provides
predictive maintenance data and reduces downtime.
One-Button Auto-Calibration: Simplifies setup and commissioning, reducing human error and time.
Selectable Valve Characterization: Allows for in-field selection of flow characteristics (Linear,
Equal %, Quick Open).
Hazardous Area Certified: Approved for use in explosive atmospheres (ATEX, IECEx, FM).
Low Air Consumption: Optimizes plant energy usage.
