                The self-lock float collar/shoe is another model worth being recommended. Its valve body is the mature back pressure valve structure, safe and reliable. There is some difference at the top of valve body ( bumping part) from the conventional ones in that the convex part is designed with groove and sealing structure, and the stop ring and sealing groove(sealing ring) are at the entrance point of self-lock plug. When mud is injected, release the plug, the plug head is inserted on the valve and locked by the retainer groove, After years application, this kind of float collar/shoe is safe and reliable, easy for operation.
