This groove extends only in a part ofthe major length of the valve and receives two round locking bars which are inserted inthe groove by way of a center cavity. An outer sealing element hermetically closes thegap between the cover and the body and the two cavities. Application of the device inburied valves exposed to corrosive atmospheres.
