3.4 Description
The GEMÜ 343 is a motorized 3/2-way globe valve with a
hollow shaft electric actuator. The eSyDrive hollow shaft ac-
tuator can be operated as ON/OFF or with integrated posi-
tioner or process controller. The valve spindle is sealed by a
self-adjusting gland packing providing low maintenance and
reliable valve spindle sealing even after a long service life. A
wiper ring fitted in front of the gland packing protects the
seal against contamination and damage. An integral optical
and electrical position indicator is standard.
3.5 Function
The product controls or regulates (depending on version) a
flowing medium by being closed or opened by a motorized
actuator.

The optical position indicator indicates the OPEN and
CLOSED positions.
