In addition to both threaded-pipe and flanged connections, sterile, standard-compliant connections for instruments are now also possible in the form of a clamp connection (DIN 11 864-3). The standard material for wetted parts is 1.4435 stainless steel, and special materials, such as 1.4539 stainless steel or Hastelloy, are also available. The 981.51 diaphragm seal (photo) is especially suitable for applications in the pharmaceutical and food industries, as well as for painting lines. The patented inline seal is notable for its cylindrical construction, enabling it to be mounted directly into pipelines and making it self-draining. — WIKA Alexander Wiegand GmbH & Co.
