Typical Healthcare & Medical Applications:
Respiratory devices such as spirometers, ventilators, air blenders, anesthesia equipment, hematology analyzers and sanitary pharmaceutical applications

Materials Specific to Healthcare & Medical
We offer a range of elastomeric materials specifically for life sciences applications which allow the diaphragm to be used in practically all liquid and gaseous media, while standing up to even the most rigorous sterilization processes.

Use of Diaphragms

Diaphragms are used in a variety of medical, pharmaceutical and biotechnology applications, particularly in low pressure valves. In a typical valve application, the diaphragm’s sealing bead seals the valve when it is in its ‘at rest’ position, similar to a static gasket or O-Ring . An actuator lifts the diaphragm, opening the valve to allow fluid flow. When the actuator is de-energized, a spring is typically used to return the diaphragm to its static position.
