CRANE ChemPharma, Saunders not only invented the
diaphragm valve concept, but has been involved in
the early stages of the application of the elastomer
sealing technology that the design depends upon.
This experience dates back to the late 1930s and
development of the first synthetic elastomers which

Thediaphragm is thekeyperformance componentwithina
diaphragmvalve. Thediaphragm formsboth thedifferential
seal and atmospheric seal and isolates the topworks from
the process media. This is especially significant in the bio-
pharm industry that requires reliable seals for both flow
control andalso tomaintain system integrityand sterility.
