The GEMÜ 5542/2-way angle seat globe valve has a plastic piston actuator and is pneumatically operated. The valve spindle is sealed by a self-adjusting gland packing or a compact seal cartridge, depending on the size and version. A wiper ring or the wiper contour of the seal cartridge additionally protects the valve spindle against contamination and damage. This provides low-maintenance and reliable spindle sealing even after a long service life.

Freeze-drying installations

In order to preserve food, paints, drugs or other hydrous substances and / or to powder them, they must be partly or completely dehydrated. The procedure used is a combination of vacuum and cold. As the amount of the required product and the properties of the products as well as the on-site conditions may be very different, not only a large number of standardized installations are used but also individually specified installations.
