Abstract
The invention starts from such a conventional ball valve assembly which includes a valve body, a valve ball, each pair of unions, body caps and cap nuts arranged symmetrically at the both sides of the said valve ball. There are provided retaining plates or pins extending laterally for positioning the unions relative to the valve body. These small retainer plates or pins are inserted through perforations formed through the wall of the valve body. In addition, the unions are formed with ring grooves adapted for receiving the root portions of these retainer plates or pins.
