UTM Smart Positioner

Utmost U529 series smart valve positioner adopts the newest advanced micro processing and intelligent measurement and control technology, based on 3 / 3 slide nozzle baffle valve and solenoid valve technology, with single and double-acting, Hart, remote transmission, flameproof, explosion-proof function, developed by China valve oem intelligent positioner and the United States R&D team, verified under the harsh operation conditions, has achieved good performance.


UTM Smart Positioner Features

  • Single/Double acting;

  • Greatly enhanced the instrument air adaptability and anti-fouling ability(water, dust, and oil), with Nozzle baffle I/P structure;

  • Smart positioner flow characteristics can be free setting (linear, quick opening, equal percentage,) and easy to control;

  • Safe, reliable, practical with equipped with a built-in LCD screen and integrated debugging button;

  • Fast self-diagnosis (2-3 minutes to complete the whole stroke);

  • Digital valve positioner, limit switches, and other internal electrical modules can be integrated; 

  • Easily remote for smart positioner for control valve checking and diagnosis with Hart communication module;

  • High adjustment precision, can realize the accuracy of 0.1% intelligent valve control with intelligent control algorithm;

  • Three valve termination and three fault reset functions can be achieved;

  • Low power consumption (25L/h I/P low power consumption, low air consumption: locator);

  • Data backup and storage functions, effectively solve the problem of online replacement, debugging;

  • Meet IEC534 (NAMUR).
