Advanced-performance kelly mud saver valve

The Mud-Chek AP mud saver valve is designed to eliminate the undesirable loss of drilling fluid when making a connection. Placed on the end of the kelly, it opens from pressure when the rig pumps are engaged, enabling circulation down the drill string. The valve closes when circulation is stopped, trapping the drilling fluid inside the kelly, thus making drill string trips drier, faster and safer.
