The quarter-turn actuators of the SQ series have been designed for the service “(On – Off) on-off” and the positioning service (classes A and B).
The opening angle can be continuously adjusted within the ranges indicated.
-Torque protection, protects the actuator against overload or obstruction of the valve.
-Programmable race ends.
Motor over-temperature protection (140 ºC).
-Display positioning closed, open, intermediate (optional).
•Internal resistance of heating, reduces the formation of condensate.
-IP68 means protection against flooding up to a maximum of 8 M.C.A. for a maximum time of 96 hours. Up to 10 operations are possible during immersion.
Working stresses (Page 70):
Three-phase (VAC): 220; 230; 240; 380; 400; 415; 500; 525; 660; 690 (50 Hz).
Single-phase (VAC): 230 (50Hz).
-DVC: 24; 48; 60; 110; 220.
•Remote (distance): Using external switches, SCADA or closed loops using a PLC (PID).
•Local: Using hand-held pendant stations located on the computer or external enclosure.
•Manual: This medium is used before the power outage, and can trigger valve or damper through the steering wheel mechanical provided with the computer.
