摘要
The cover is fixed without the use of bolts. On each side thereof, an almost closed groove is defined in one half by the peripheral portion of the cover and in the other half by the peripheral portion of the body. This groove extends only in a part of the major length of the valve and receives two round locking bars which are inserted in the groove by way of a center cavity. An outer sealing element hermetically closes the gap between the cover and the body and the two cavities. Application of the device in buried valves exposed to corrosive atmospheres.
