Part-turn actuators

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, 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.
