Characteristics

Designation:

RemTEK is used to control translatory moving valves at oil and gas facilities 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 and safety circuits (SIL2) to control isolation shut-off or control pipeline valves.

Functions:

  • In-built 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 contacts.

Features and Benefits:

  • Position regulation at low speed and fast cut-off when safety signal is on;
  • Compact size and monoblock design of the electric motor and electronic control unit;
  • Energy efficiency due to the built-in frequency converter;
  • Highly reliable cycloidal transmissions and transmissions with intermediate rolling elements, ball-screw units;
  • 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.
