Characteristics

Designation:

Electric drives are used to regulate and cut off flows in modular equipment and in process plants at oil and gas facilities.

The compact design provides a number of advantages in the design of process units.

Electric drives are used in explosive zones of class 1 and 2 in accordance with GOST R 60079 (in explosive zones of all classes), where may be formed vapor- and gas-and-air explosive mixtures of IIA and IIB groups T1, T2, T3, T4 as per the classification of GOST R IEC 60079-20-1.

RemTEK is used in ESD systems, safety circuits (SIL2) to control isolation shut-off or control pipeline valves.

Functions:

  • Electronic limit and torque switches;
  • In-built frequency converter for motion control;
  • Reliable mechanical gears;
  • Bringing to a safe position function;
  • Analogue and discrete control;
  • Control and setting via interfaces;
  • Intelligent monitoring and protection systems;
  • Absolute electronic position sensor;
  • Nonintrusive set up;
  • No mechanical contact.

Features and Benefits: 

  • High-efficient self-controlled synchronous electric motor with permanent magnets;
  • In-built frequency converter;
  • Cycloidal gearboxes and gearboxes with intermediate rolling elements;
  • Universal control unit for all modifications of electric drives;
  • Increased resource;
  • High reliability and fail safety;
  • Self-diagnosis, built-in archiving of emergency events;
  • Embodiments provided with safe state function (NO/NC) with built-in energy storage on supercapacitors;
  • Supply voltage: 230 V or 400 V;
  • Partial valve stroke test (PST-test);
  • Functional safety SIL2;
  • In-built WIFI interface; 
  • Ready to “Digital Economy”, “Industry 4.0 Ready”;
  • Double insulated connection box;
  • Compliance with the requirements of STO GAZPROM 2-4.1-212-2008 for the time of overlapping ball valves.
