Flowserve valve positioners are smart electro-pneumatic tools designed to guarantee the optimal position of the final control component – a valve – in response to instructions provided by a process controller. These positioners convert a conventional input signal (such as 4-20 mA) into accurate pneumatic pressure output required to activate the valve. This process enables the valve to counteract stem friction and dynamic forces efficiently, resulting in superior control precision.
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).
