SAX31.., SAX61.., SAX81.. are three motor actuators, which can be used for 20mm stroke Siemens 2-port and 3-port valves, and have position feedback, forced control, selection of flow characteristic and other features
This document provides engineering data for Siemens electromotoric actuators, specifically models SAX31.00, SAX61.03, and SAX81.03. These devices are designed with a 20 mm stroke for direct mounting on various Siemens valve types to serve as control and safety shut-off valves in heating, ventilation, and air conditioning systems.
The data sheet details electrical specifications, including operating voltages (AC 230 V or AC/DC 24 V), positioning times ranging from 30s to 120s, and a maximum positioning force of 800 N. It also covers compatible valve combinations, environmental conditions for operation and storage, available accessories like potentiometers and stem heating elements, and connection diagrams.
