Electric drives of fire-retardant valves and valves of smoke removal

Electric drives are intended for control of fire-retardant valves and valves of smoke removal in systems of ventilation and conditioning.

Drives are equipped:

- the mechanism of manual control (for testing of the valve at powered off);
- the built-in returnable spring (except BE series drives...);
- two built-in additional contacts (for the alarm system of position of the gate of the valve at angles of rotation 5 ° and 80 °);
- the thermoelectric breaker (for BF24-T, BF230-T, BLF24-T, BLF230-T drives) which disconnects a chain of electric power supply of the drive at a temperature in the channel or out of its 72 °C.
