Diaphragm / slotted disc

Scope and limits

Diaphragm / slotted disc — geometry, declared design limits and explicit qualification gaps. Supplier/test force–travel curve for the actual assembly and operating conditions. Piecewise linear interpolation only inside its recorded range; no extrapolation or inferred material law. Slot-tip stress, lever ratio, contact and snap-through need a nonlinear shell/contact model and tests.
