The GEMU 534 2/2-way globe valve has a plastic piston actuator and is pneumatically operated. 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.
