It will be apparent that not all applications can be suited by standard
product and it is a Benoil speciality to produce discs to meet particular
needs, often in very small numbers. Sometimes these are the result of a
direct customer design request, sometimes a mere modification of a standard
design, sometimes they arise from the testing for a specific application
as above. In all these cases, it is of great importance to define the
parameters carefully with a customer to achieve the desired result, as
quickly as possible, and at reasonable cost.

A particular example illustrates the point. Disc assemblies can be made
to operate at different pressures in the two directions. Thus one can
build safety into a disc which must operate in the desired sense at a
known pressure, but must be protected from a reverse burst, from say
a surge. Clearly, such are tailored to the customer need.

Again, it may be required to ensure a tight minimum value and for one customer
application we ensured all discs were tested to 98% of the nominal in the
laboratory before despatch.

Benoil has also made certain special holders and equipment that incorporate
discs, including a special sub with a welded disc across it.
