  • Safety choke valve
    Patent number: 4926898
    Abstract: The invention relates to a safety chock valve having improved body top. An upper part of the valve body has a tapered wall cavity which receives in a sealed engagement a tapered lower part of the valve bonnet. An internally threaded cap member secures sealed position of the bonnet on the valve body. Even partial disengagement of the threads causes breaking of the sealed engagement and escape of pressure between the valve body and the bonnet.
