Product Description:
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.
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.
