JM 300 Top Drive Valve

The Premium Oilfield Technologies JM 300 Top Drive Valves can be used for both blow out prevention and mud control during drilling operations. Our manually or hydraulic crank operated kelly valves are installed at each end of the kelly, or below the top drive, to control flow from the wellbore and protect surface equipment from high pressure kicks. The compact one-piece design is ideally suited where space is at a premium or where handling weight is critical. Its smooth OD allows this valve to be run anywhere in the drill string
