Double Function Arrow-shaped Back Pressure Valve Type SJF

Model “SJF” Double Function Arrow-shaped Back Pressure Valve is a integrated tool which has

functions of both the arrow-shaped back pressure valve and the mud globe valve. When used,

the tool can not only prevent down-hole kick from blowout, but also prevent the mud in the

Kelly and hose from flowing out, thus reducing mud loss and ensuring a clean of rig floor.

Type FF Float Sub/Float Valve

Model “FF” Float Sub is a new-style drilling tool inside blowout prevent. During normal

drilling, valve open, drilling fluid circulation clearly while down-hole happen to kick or blowout.

The valve cap shut off in order to achieve blowout prevention. When tripping in or out, it

preventing drilling fluid flowing from back and prevent mud entering into the drill string,

realizing the function of preventing block. It is a special tool for preventing blowout and block in

drilling operation.
