IQT - Part - turn 'Backup

IQT fail-safe actuators in the ac supply fails, provide valve fault running through the use of battery energy.Under the condition of normal function, actuator by alternating current supply to perform operations.When breaking the supply, actuator automatic conversion on 24 v direct current supply, allowing the valve control, reach the fail safe position.

IQT fail safeType 1 - external fail safe

Applicable to dangerous or hazardous area, type 1 including provide based on normal ac 24 v dc supply.

IQT fail safeType 2 - battery fail safe

Only suitable for the danger zone, type 2 is included in the battery inside the actuator terminal cover, and when the ac power supply, through the complete finished charging charging system.

IQT fail-safe provides the following functions:

• Performance is the same as the standard IQT
• Single-phase and three-phase, direct current supply (type 1)
• External regulation of the optional
• Rotary, and multiple ports are optional
