Flowserve Logix® 3200MD / 3200MD+ Digital Positioner
The Flowserve Logix® 3200MD Series is a family of two-wire, 4-20 mA input digital valve positioners that utilize the HART communication protocol . Employing state-of-the-art piezo technology, these positioners are designed to deliver superior performance and reliability for the precise control of both double- and single-acting actuators with linear or rotary mountings .
The Logix 3200MD+ is the enhanced version of the series, building upon the core features with advanced diagnostics and broader HART compatibility .
Key Features & Benefits
Easy Configuration and Calibration: Setup is simplified through a local user interface featuring status LEDs, DIP switches, and calibration buttons. Configuration can be done locally, via a HART handheld communicator, or through Flowserve's SoftTools software (or ValveSight™ DTM for the 3200MD+) .
HART Communication: The 3200MD supports HART 5 protocol . The 3200MD+ enhances this by supporting HART 5, 6, and 7, enabling two-way remote digital communication for configuration, monitoring, and diagnostics over the standard 4-20 mA signal wires .
Advanced Diagnostics:
The base 3200MD offers standard self-diagnostics.
The 3200MD+ is a significant upgrade, equipped with over 100 helpful warning alarms that can alert users to potential failures in the valve, actuator, or positioner itself, helping to prevent plant upsets .
When used with ValveSight™ DTM Software, a comprehensive suite of diagnostic tools becomes available to quickly diagnose problems, monitor valve health, and perform offline tests .
The Flowserve Logix® 520MD Series is a family of high-performance, two-wire digital valve positioners that utilize the HART communication protocol. Designed to provide precise and reliable control for both linear and rotary pneumatic actuators, these positioners are engineered to withstand severe industrial environments .
The Logix 520MD+ is the enhanced version of the series, building upon the core features with advanced diagnostics and improved performance
The Flowserve PMV D3 is a digital valve positioner that operates on the FOUNDATION Fieldbus protocol, offering unmatched performance and reliability in all areas of control and automation . Its modular, scalable design allows users to select options best suited for specific applications
The PMV P5 (Pneumatic) and PMV EP5 (Electro-Pneumatic) are analog positioners known for their robust, compact design and reliable performance in diverse environments . The EP5 is adapted from the P5, adding an I/P (current-to-pressure) converter to accept a standard 4-20 mA input signal
The PMV F5 is a feedback unit uniquely designed to mount directly on top of the PMV P5, EP5, or P-2000 positioners with a minimum of parts, requiring no additional brackets or linkage . It can also be mounted directly on actuators using an additional mounting kit
