摘要

The stop valve (10) has a tube structure (11) that is made of plastic and is provided with a pipe wall (38). A gap-like aperture (25) is aligned transverse to flow direction. A seal cavity (30) is incorporated in outer surface of the tube structure and is inserted into the gap-like aperture. A slider (23) is clasped by the seal cavity, for inhibiting fluid leakage from the tube structure along an obturator through the gap-like aperture. The seal cavity is provided with a seal package (31) that surrounds the slider and rests upon an outer surface of the tube structure.
