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 WAMŪ 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 WAMŪ's unique FDA-approved SINTŪ-polymer composite or a cast iron disc, and a pre-tensioned elastomer seal.

For the food industry WAMŪ offers a version with stainless steel disc and integral seal.

V1FS has a top flange and a bottom section suitable for fixing of a flexible sleeve.

V2FS has identical top and bottom flanges.

Advantages and innovative features

- Dust proof and pressure proof up to 0.2 bar (3 psi)
- Cast iron butterfly disc on request
- Food-grade version on request
