GEMÜ 543 eSyStep

The GEMÜ 543 eSyStep is an electrically operated 2/2-way angle seat globe valve. The eSyStep electric actuator is available as On/Off actuator or with integrated positioner. 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. The self-locking actuator holds its position in a stable manner when idle and in the event of power supply failure.
