Abstract
A valve device comprising a valve housing having inlet and outlet end pieces for mounting of the valve in a pipeline, and a valve member being moveable for opening and closing of the valve. The valve member is mounted in a unit which can be removed from the valve housing and which consists of a cover that can be sealingly fastened to the valve housing in which cover is mounted a rod or spindle for movement of the valve member, a retainer in which the valve member is moveable and which carries gaskets for sealing against seats in the valve housing, respectively, and the valve housing has a transverse opening and is equipped with an arrangement for locking the cover in its mounted position, in order to permit rectilinear movement of the unit into and out of the transverse opening. The gaskets can be mutually shifted axially in the retainer whereby springs are provided for urging the gaskets axially towards the seats in order to cause sealing in the assembled state, and the retainer comprises assemblies for locking the gaskets in an axially retracted position in the retainer.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
