Actuators for On - Off / Modulating” (500 - 675.000 Nm) (SA + GS)

REDUCERS FRACTION OF A TURN AND PRE-REDUCERS TO SERVICE REGULATION

The torques shown are based on the case of application of service regulation, for which you'll need a crown of bronze. For other cases of application is no documentation apart for the sizing.
The actuators multi-turn adequate that are proposed have been chosen with a view to achieving the maximum torque maximum output. If the torque requirements are smaller, you can also use actuators multi-turn smaller. You will find detailed information in the data sheets separately

RANGES OF ANGLE OF OPENING

The opening angle can be continuously adjusted within the ranges indicated.

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.
