New Pneumatic Control Valve and ASCO Solenoid Valve and FLOWSERVE 3200MD 520MD 3800MD Valve Positioner

Product Overview

The Flowserve Logix 3200MD is a two-wire, 4-20 mA input digital valve positioner that uses advanced piezo technology for precise, responsive valve positioning. It supports both single- and double-acting actuators in linear or rotary configurations, powered entirely by the control signal. Local interface options make setup straightforward, while HART protocol enables remote communication and diagnostics.

Features

• State-of-the-art piezo valve control for fast response and high reliability.
• Local status LEDs for quick visual feedback.
• Local DIP switches and calibration buttons for on-site adjustments.
• Auto tuning with dynamic gain selection for optimized performance.
• Utilizes HART 5 protocol for configuration and monitoring.
• Simple calibration via local interface or HART handheld.
• Supports analog or digital command sources (0% closed, 100% open).
