STS' AutoFill Casing Fill-Up and Circulating Tool saves time, enhances rig safety, and well control during drilling operations by allowing the operator to fill, circulate, and recover fluid while running casing.

With STS' AutoFill Casing Fill-Up and Circulating Tool, you can continue to use the rig pumps and top drive while running or pulling each joint of casing. Equipment is available in sizes from 4-1/2" to 20" casing.

Unlike all other fill-up and circulating equipment, the Auto Valve provides a "full opening" mud saver valve. This allows high fill-ups, while taking fluid in the flow-back mode, without having the well to surge.
