Original brand new Flowserve Valtek NT3000 series analog valve positioner, electrical sensor, pneumatic actuator, original brand new stainless steel positioner

Product Description:

Flowserve valve positioners are sophisticated electro-pneumatic devices designed to ensure that the valve, serving as the final control element, reaches the intended position specified by a process controller. These positioners effectively convert a conventional input signal (such as 4-20 mA) into an accurate pneumatic output pressure to operate the valve. By overcoming stem friction and dynamic forces, they enhance control accuracy significantly.

The primary function of Flowserve valve positioners is to bridge the communication gap between the control system and the valve. By receiving signals from the controller, they optimize the output pressure to precisely position the valve. This enables seamless control and response, addressing stem friction and dynamic forces that may affect the valve's performance.

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).
