1. Introduction

The most common valve found in bulk solids handling is without doubt the butterfly valve. This type of valve is simple, robuts and works globally well with the flow of bulk solids.

This page is giving details on the design of butterfly valve and their actuator.

2. Butterfly valve

The constitution of a butterfly valve is quite simple : the product flow is stopped or allowed thanks to a butterfly, a thick gasket is ensuring the tightness of the valve and an actuator (most of the case pneumatic) is allowing the valve to move.
