Pig valves are used to essentially wipe the interior of a pipe and prevent blockages. Chaoda's latest patented design is unique in that it loads from the side with a latch door that only opens after the valve has been depressurized and drained. This video was made to explain the perks and functionality of this particular design.

Chaoda USA is a valve company that wanted to showcase their product in a more interesting way. Breaking down each part of the valve is the best way to do so. I created a hierarchical part structure for the valve and was able to animate the pieces in a way that both made sense and was visually pleasing to the eye. This valve in particular is called a Metal Seated Ball Valve, because the seats that cradle both sides of the ball are made of metal as well.
