Probably the most hygienic way of isolating a flow of media is for the valve not to touch the media at all. The endless tube pinch valve operates according to this principle. The medium is channelled through a tube and the valve compresses or releases the tube pneumatically. The built-in stroke limitation prevents the tube from being overloaded.
