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.
