Abstract: A valve utilizes a composite two-piece housing to provide a low cost, high strength, light weight alternative to conventional metal and plastic valves adaptable for corrosive and non-corrosive environments. The valve includes a valve body defined by a first body half coupled to a second body half. A valve disk assembly is disposed between the first and second body halves. The disk assembly includes a valve disk, a valve stem and a valve seal. The disk stem is positioned within the valve disk along a central axis of the disk such that when the disk is rotated about the valve stem, the valve is opened or closed. The valve seal includes a primary portion lining an interior surface formed by the first and second body halves to engage an outer surface of the disk. The seal also includes a secondary portion disposed within and between the first and second body halves. The primary and secondary sealing portions configured to retain position within the housing and in sealing engagement with the disk.

Abstract: A device for sealing of conduits inserted in circular lead-throughs of walls and roofs designed as a frame is provided for the arrangement of a plug formed sealing body of elastic material which forms a quadrangular pack accommodation. In the pack accommodation elastic splitted modules in square form are inserted with received conduits and arranged sealingly by clamping elements acting on the sealing body. To increase the pack accommodation for an assembly and disassembly of the modules it is so provided, that at least one boundary side of the pack accommodation forms a free space for receiving an insertable part element after assembly of the modules. The part element forms a part of the sealing body and is designed as horizontal segment of a part of the depth of the sealing body.
