VFS - Butterfly Valves
Description and working principle
For closing bins, hoppers and silos containing powders or granular materials, or to close screw conveyor outlets, Butterfly Valves still are and always will be among the most widely used equipment.
What used to be custom-built items for specific applications, have been turned by WAM® into a mass-produced industrial product with features that allow versatile use.
Performance and technical features
VFS Butterfly Valves consist of two high-pressure die-cast semi-bodies made from aluminium alloy, either a steel core disc coated with WAM®'s unique FDA-approved SINT®-polymer composite or a cast iron disc, and a pre-tensioned elastomer seal.
