The GEMU 536 2/2-way globe valve has a rugged low maintenance membrane actuator and is pneumatically operated. The valve is particularly suitable for use as a control valve. The valve plug is fixed to the spindle in such a way as to allow flexing during closure to ensure tight shut-off. 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.
