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
