The GEMU 532 2/2-way globe valve has a robust low maintenance aluminium 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. Compared to GEMÜ 512, the actuator flange for attaching the actuator is omitted.
