Efficient and reliable material flow interception

VW Butterfly Valves are the ideal solution for the interception of gravity-fed or pneumatically conveyed dry powders or granules in a variety of bulk solids handling and processing plants.

VW Butterfly Valves consist of a single block body manufactured from die-cast aluminium, a carbon steel or stainless steel disc including shafts, and an elastomer seal. An adjusting lever or pneumatic or electric actuator can be applied to the valve. The three WAM-type actuators are perfectly interchangeable. Interchangeability of the drive shaft (standard: DIN 5482; option: ISO 5211) and universal connection to different size flanges results in variety of configurations.

Function :

• VW Butterfly Valves are used in virtually all types of bulk solids processing plants where interception of gravity-fed or pneumatically conveyed dry powders or granules is required.
• This type of valve is particularly suitable for pneumatic conveying operations, in both dilute and dense phase applications, provided the operating pressure does not exceed 2.5 bar (36 PSI).
• Due to its particular design features and the materials used, the VW Butterfly Valve represents the ideal solution in many cases, both from a technical and an economic point of view.
