WIKA

990.26 Flanged Process Connection Diaphragm Seal

The WIKA 990.26 diaphragm seal is ideally suited for applications with small process connections. Due to the internal diaphragm, low measuring ranges can be realised — the large diameter of the diaphragm affects a lower deviation at the measuring instrument when the temperature changes.

The WIKA 990.26 diaphragm seal is ideally suited for applications with small process connections. Due to the internal diaphragm, low measuring ranges can be realised — the large diameter of the diaphragm affects a lower deviation at the measuring instrument when the temperature changes.

Mounting of the diaphragm seal to the measuring instrument may be made via a direct connection, for high temperatures via a cooling element or via a flexible capillary.

For the material selection, WIKA offers a variety of solutions, in which the upper body of the diaphragm seal and the wetted parts can be made of identical or different materials. The wetted parts can, as an alternative, be coated.

  • Suitable for corrosive, highly viscous, crystallising or hot pressure media
