GEMÜ 548 motorized angle seat globe valve

Category Brand


The GEMÜ 548 2/2-way angle seat globe valve has a motorized actuator with a plastic housing. The motor is designed for DC and AC operating voltages. The integrated gear translates the rotary motor movement into a linear movement. The actuator is available as an on/off version or with an integrated positioner and additional 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.
