Description
The GEMÜ 549 eSyDrive is a motorized 2/2-way angle seat
globe valve with a hollow shaft electric actuator. The eSyDrive
hollow shaft actuator can be operated as On/Off or with integ-
rated positioner or process controller. The valve spindle is
sealed by a self-adjusting gland packing providing low-main-
tenance 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 in-
tegral optical and electrical position indicator is standard.
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 has an optical position indicator as standard. The
optical position indicator indicates the OPEN and CLOSED po-
sitions.
