V401 Couplings

Download PDF Data Sheet

TVN V401 Couplings are the flexible solution for joining pipes. These couplings are ideal for absorbing noises and vibrations in pipelines and overcoming axial o set, guaranteeing a permanently leaktight connection. It is a connection part enables the necessary repair and modi cations on the pipelines, connecting pipes with different type and diameter. Supplied as standard with EPDM gasket for water applications. Each rubber gasket is contained in a compression chamber which is formed by the follower end rings, middle ring and pipe surface. By tightening the coupling‘s bolts, the follower end rings are drawn together, thus reducing the volume of the compression chambers and compressing the gaskets, resulting in a pressure tight seal. The TVN coupling allows an expansion and contraction of ±2,5 mm and an angular deflection of 3° for each gasket (± 5 mm & 6° in total for each coupling).
