INTRODUCTION

GTD 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.

 

TECHNICAL SPECS

Description

GTD Butterfly Valves consist of a single block body manufactured from die-cast , 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 type actuators are perfectly interchangeable. Interchangeability of the drive shaft (standard:  ISO 5211; option:DIN 5482) and universal connection to different size flanges results in variety of configurations.

 

Function

GTD 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 10 bar (145PSI). 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.
