3.2 Description
The GEMÜ 649 diaphragm valve is actuated by a motorized
hollow shaft actuator. It is based on technology that does not
use brushes or sensors and therefore guarantees high per-
formance and a long service life. In addition to OPEN/CLOSE
applications, the valve is ideal for variable and complex con-
trol applications. The actuator has an integrated web server
for parameterization and diagnosis purposes.
3.3 Function
The product controls or regulates (depending on version) a
flowing medium by being closed or opened by a motorized ac-
tuator.
The product has an optical position indicator as standard. The
optical position indicator indicates the OPEN and CLOSED po-
sitions.
