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:

Ensures precise valve positioning (< ±0.5%) for improved process control.

Supports HART, Foundation Fieldbus, and Profibus-PA protocols for seamless integration into digital control systems.

Features rugged housing (e.g., NEMA 4X / IP66) and corrosion-resistant materials for harsh environments.

Built-in monitoring of travel, pressure, and supply air provides predictive maintenance data and reduces downtime.

Simplifies setup and commissioning, reducing human error and time.

Allows for in-field selection of flow characteristics (Linear, Equal %, Quick Open).

Approved for use in explosive atmospheres (ATEX, IECEx, FM).

Optimizes plant energy usage.
