DISTRIBUTING SLIDE VALVE FOR LABORATORY PURPOSES

摘要

A distributing slide valve comprises a spindle consisting of at least one pair of conical truncated discs secured on an actuating rod. The pair of discs defines in respect of the valve bore an annular space for receiving a sealing ring and pressure means are provided to apply a force to the discs and to urge the rings against the bore. Each ring contains a system of individual ducts adapted to establish fluid communications between a system of fluid conduits which are to be operated by a valve.
