Ball valve, exploded view and cutaway

What it is

A flanged, trunnion-style ball valve I designed from scratch. In 16 seconds the bolts back out, the end caps slide off, the seats, ball and stem come out, it goes back together, and then a half-section shows the ball turn from closed to open with flow through the bore.

The same model also exports small enough for a phone, so a buyer can put the valve on a desk at real size.

How it was made

• MaterialsOxide-red paint with worn edges, machined steel faces, a polished chrome ball and white PTFE seats.
• MotionStaggered and eased: fasteners first, then the caps, seats, ball and stem. No part passes through another.
• Render384 frames in Blender EEVEE, 2.3 seconds a frame on average. About 15 minutes.
• WebThe same model exported at 290 KB for the AR files on iPhone and Android.
