球心截止阀 539 eSyDrive

电动控制制动

The GEMÜ 539 2/2-way globe valve has a hollow shaft actuator and is electrically operated. The eSyDrive hollow shaft actuator can be operated as an OPEN/CLOSE actuator or as an actuator with integrated positioner 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.
