The GEMU 312 3/2-way globe valve has a rugged low maintenance aluminium piston actuator and is pneumatically operated. The double-sided valve plug is connected to the actuator via a 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.
