We like to offer special qualities on demand.

The resistance of the materials above is depending on the concentration and temperature as well as on the operation pressure of the process media.
Threaded parts vulcanized into rubberlinings building the bolt connections to the control spindle of the armature on one side and on the other to the valve body.
With it a controlled operation is made so that the rubber linings - also with sticky media and media tending to incrustation - always open faultlessly.
By the squeezing operation unwanted deposits will be detached and flowing off.

These high class lining and mould parts are produced in steel moulds due to decades of experience. Fabric linings in polyamide fabric are integrated onesided on the upper side to reinforce the rubber lining and are vulcanized.

The close cooperation with our rubber laboratory and available resistiveness lists aim to determine the most resistive rubber composite and quality for specific needs and cases of operation.
The rubber lining is only in contact with the process medium.
After the replacement of this spare part, to which there is a mounting instruction available - see product selection „technical documentation“ - our customers have again a armature as good as new.

Please quote the medium, concentration, temperature,
max. and min. working pressure in inquiries and orders.

We reserve the right to alter technical data.
