AMETEK developed the Type SCW Series flange-attached diaphragm seals for applications requiring control of fugitive emissions and for leak protection against toxic and explosive media as defined the EPA Clean Air Act of 1990.
The SCW seals are all-welded with stainless steel housings* and continuous duty convoluted diaphragm. They feature an ANSI standard slip on flange for easy installation. The top housing is welded to the bottom, providing a permanent seal without a gasket.This seal is also available HASTELLOY® C, MONEL®, and other materials (consult factory)
