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.
