Flowserve Logix 420, LOGIX 420-14-W1D-1, and 3200MD Intelligent Explosion-Proof Valve Positioners

Product Description:

Flowserve valve positioners are advanced electro-pneumatic devices designed to facilitate precise control of the final control element – a valve. Their primary function is to ensure that the valve moves to the intended position instructed by a process controller. These positioners effectively convert a conventional input signal, such as 4-20 mA, into an accurate pneumatic output pressure. This pressure is then utilized to operate the valve, overcoming obstacles like stem friction and dynamic forces to guarantee superior control accuracy.

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.
