The GEMU 354 3/2-way globe valve has a rugged, low-maintenance plastic piston actuator and is pneumatically operated. The connection for the control medium can be rotated through 360°. The double-sided valve plug is connected to the actuator via a valve spindle. The valve spindle is sealed by a self-adjusting gland packing providing low-maintenance and reliable valve spindle sealing even after long service life. A wiper ring fitted in front of the gland packing protects the seal against contamination and damage.
