Catalog of sight glass fittings and discs
The catalog is organized by mounting method and construction type. Each section explains which solutions belong to the category, how they differ and which data a correct selection requires.
Model cards are published only for documentally confirmed products; today the catalog contains construction classes and series — sufficient for a correct selection and a complete inquiry.
