Saddle And Socket Diaphragm Seal (S26Vn) - ABB S26 Series Operating Instruction

5.12 Saddle and Socket diaphragm seal (S26VN)

The saddle and socket seal are the best solution when the diaphragm needs to be as closest as possible to the process media.
These are typically installed by welding to the process pipes with fluid at high viscosity. Saddle and socket process connection
fittings are available as option selection, available only in AISI 316 L ss.
