Sealing type of air source ball valve

What are the sealing types for pneumatic ball valves? I have a diaphragm here (Hastelloy C) – I don’t understand what that means

Bellows sealing can only be used when the valve stem moves up and down.

Ball valves rarely use bellows; HA C is the material for bellows. The bellows is welded between the stuffing box and the valve cover. I hope this helps you.
