| description | A guillotine valve, used for example in pipelines includes a single block body incorporating sealing elements, each in the form of an annular hose section, which are made of an elastomeric material and which are hollow along their entire circumference, each providing an airtight pneumatic circumferential chamber filled with air. Due to the compressibility of the chambers the contact faces of the hose sections deform uniformly in relation to a closing blade. Convex contours on the internal faces of the hose sections result in a further sealing effect due the pressing together of the contact faces by the pressure of the pipeline fluid. The hose sections can each also incorporate a T-shaped metal core comprising an axial portion and a radial portion. |
