Abstract
A valve has a molded plastic valve housing defining an inlet port, an outlet port, and a chamber between the ports.

A molded plastic valve body is rotatable about a body axis between open and closed positions in the chamber and is unitarily formed with a throughgoing passage aligned with the ports only in the open position, a stem extending along the body axis through the hole of the cap, axially oppositely open mass-reducing pockets, and an annular rim captured between the cap and the collar.
