PVC-U & PVC-C VALVES Concept & typical application Concept et applications typiques Concepto y aplicaciones Conceito e aplicações Shuts off flow by means of a cone pushed by a spring which helps it to obtain an entirely watertight closure. The difference in pressure between two points of the installation is able to overcome the resistance of the spring, thus making the fluid flow in the desired direction and preventing the flow passage in the other. Transported material • Clean liquids, not viscous and without containing particles. Installation • Horizontal or vertical. Materials • Metallic...
