A buoyant float including a body having an interior defined in part by a side wall and a bottom extending inward from the side wall. The side wall has an upper edge defining an open top of the body. The float includes a cover sized and shaped for covering the top of the body. The cover attaches to the body to maintain the cover in position relative to the body to cover the open top. The cover has a tubular skirt extending downward and around the upper edge of the body side wall when the cover is in position covering the top of the body. An air pocket is created at an interface between the cover and the body when the float is positioned in liquid to isolate the interface from the liquid and prevent liquid from entering the hollow interior of the body through the interface.

Float

Automatic drain valve

A drain valve including a housing having a float chamber, a piston chamber, and a plenum communicating with the piston chamber through a seat. The housing has a liquid inlet passage, and an outlet port. The drain valve has a tube passage communicating with the piston chamber. The drain valve includes an annular float. The drain valve includes a seal body connected to the float and rising away from the tube passage when liquid is in the float chamber. The drain valve includes a piston slidably mounted in the piston chamber having a head that moves away from the seat when gas enters the piston chamber. The piston includes a valve element that moves as the piston head moves to expose the liquid inlet port and allow liquid to flow from the liquid inlet passage through the plenum and into the liquid outlet passage.
