Product Description:
Flowserve valve positioners are advanced electro-pneumatic devices
designed to guarantee that the final control element, a valve,
accurately reaches the specified position instructed by a process
controller. These positioners convert a typical input signal, such
as 4-20 mA, into a precise pneumatic pressure output to activate
the valve. This functionality enables them to effectively manage
stem friction and dynamic forces, delivering exceptional control
precision.
By utilizing intelligent technology, Flowserve valve positioners
play a crucial role in ensuring seamless operation and enhanced
efficiency in industrial processes. Their ability to interpret and
execute commands accurately enhances the overall reliability and
performance of control systems. They are instrumental in
controlling the movement of valves, overcoming any resistance or
fluctuations to maintain consistent and precise positioning as
required.
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.
