3.3 Description
The GEMÜ 639 is a motorized 2/2-way diaphragm valve. The
eSyStep electric actuator is available as ON/OFF or with integ-
rated positioner. An integral optical and electrical position in-
dicator is standard. The self-locking actuator holds its posi-
tion in a stable manner when idle and in the event of power
supply failure.

3.4 Function
The product controls or regulates (depending on version) a
flowing medium by being closed or opened by a motorized ac-
tuator.
The product is equipped as standard with a mechanical posi-
tion indicator as well as an electrical position and status indic-
ator.
4 GEMÜ CONEXO
Order without CONEXO
If you have ordered the product without CONEXO functionality,
the RFID chip is used for traceability in the production process
and quality assurance. Expansion to include the CONEXO
functionality at a later date must be coordinated with GEMÜ.
Order with CONEXO
GEMÜ CONEXO must be ordered separately with the ordering
option "CONEXO" (see order data).
For electronic identification purposes, each replaceable com-
ponent contained in the product is equipped with an RFID chip
(1). Where you can find the RFID chip differs from product to
product.
