990.12 Flanged Process Connection Diaphragm Seal

  • Item #: 2270

Product Description

The WIKA 990.12 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. By means of optionally available flushing connections, the process side of the flange can be cleaned and flushed as required.

Assembly 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, the extended diaphragm and the wetted parts can be made of identical or different materials. The diaphragm and the extended diaphragm can, as an alternative, be coated.

Applications

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