The GEMÜ 639 eSyStep is an electrically operated 2/2-way diaphragm valve. The eSyStep electric actuator is available as On/Off actuator or with integrated positioner. 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.
