The Flowserve Logix 3400MD is a high-performance digital valve positioner designed for precise and reliable process control in demanding industrial environments. Utilizing advanced piezo technology and a 32-bit microprocessor, it delivers superior response and stability. The positioner supports the Foundation Fieldbus (FF) protocol for seamless bidirectional communication and integration into modern digital control systems.
Its standout feature is the user-friendly, tool-free setup. With the onboard QUICK-CAL™ button, DIP switches, and LED status indicators, technicians can complete valve calibration and configuration within minutes without handheld devices. This is complemented by powerful predictive diagnostics available through ValveSight™ software, which proactively monitors for potential valve issues.
Built for harsh conditions, the Logix 3400MD is housed in a robust IP65 enclosure (dust-tight and protected against water jets) and holds multiple explosion-proof certifications (e.g., Ex d, Ex ia), making it suitable for use in hazardous areas. It operates on a standard 4-20mA signal within a wide temperature range and controls both single-acting and double-acting actuators for linear or rotary valves, offering exceptional versatility across industries such as oil & gas, petrochemical, and power.
