Actuators for On-Off / Modulating" (60 - 16.000 Nm) (SA + GST)

Gear reducers cylindrical GST

When the input shaft must work shifted with respect to the output shaft, are used combinations of actuators multi-turn SA with the gear reducers cylindrical GST of AUMA.

This allows you to multiply the output torque.

Main features:

-Torque protection, protects the actuator against overload or obstruction of the valve.

-Programmable race ends.

Motor over-temperature protection (140 ºC). 

-Closed, open, intermediate positioning display (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.

Types of command for operation:

•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.
