Flowserve Logix 3800 Digital Positioner

Flowserve Logix 3800 Digital Positioner

The Logix 3800 digital positioner helps plant owners and operators maximize production while minimizing operating costs.

Compatible with linear and rotary valves and actuators, the robust design of the Logix 3800 delivers high reliability in tough environments. It provides unparalleled modularity and versatility within a single unit. Its ability to handle double- or single-acting, linear and rotary applications reduces inventory costs and contributes to a lower total cost of ownership. Installation is simplified with an innovative, one-button quick calibration feature.

Users will also realize improvements in process uptime, reliability and process throughput. Advanced diagnostics not only identify developing problems in the control valve, but also help guide corrective actions to ensure reduced return-to-operation times.

Maximize production with the new Logix™ 3800 positioner, with the new Logix 3800 Positioner, you get it all — powerful diagnostics, reliable performance and simple configuration and calibration. This high-precision tool helps plant owners and operators maximize production while minimizing operating costs.

Improve Uptime and Throughput with Sensing Technology

The advanced predictive diagnostics of Logix 3800 include five intelligent pressure sensors, powered by ValveSight DTM, that identify developing problems in valves and actuators. This enables operators to better assess and prioritize corrective actions, which means proactive management of downtime and throughput.

Get Reliable, Safe Performance in all Applications

Featuring unique modularity and versatility in a single unit, the robust design of Logix 3800 delivers higher reliability in the demanding environments of the oil and gas, chemical, power and some manufacturing industries. The positioner’s dual-element feedback sensor is contactless, which limits the number of moving parts. Plus, it can handle single- or double-acting, linear and rotary applications with minimal air consumption. These features help plant owners and operators reduce both inventory and operating costs.

Safe operation is of paramount importance, and the Logix 3800 digital positioner offers SIL 3 certification. And for the most extreme environments, Logix 3800 is available with ATEX/IECEx explosion-proof, intrinsically safe, non-incendive housing options.

Avoid Installation and Configuration Issues from the Start

With Logix 3800, installation and configuration are easy. Its adaptable design not only enables integration with industry-leading communication technologies such as Analog, HART, Foundation Fieldbus, 4-20 or discrete I/O signals, but it also allows for direct mounting to VDI/VDE standards without the need for external tubing. Plus, commissioning is simplified with the on-board Quick-Cal™ button: this one-button setup automatically configures the zero, span and gain of the positioner for most valves in less than 60 seconds.
