The Composite Valve is a high-performance solution engineered for precision powder dosing, bulk discharge, and volumetric control. It is particularly well-suited for pack-off systems that demand both speed and accuracy in powder handling.

Innovative Dual-Function Design
This advanced valve combines two functions in a single compact unit:

• Main Leaf (Butterfly Operation): Handles the bulk discharge of powders with smooth, controlled flow.
• Dosing Head (Miniature Dosing Valve): Dispenses precise, tiny quantities during the final dosing stage for exceptional accuracy.

A 4–20mA positioner on the main leaf allows proportional closing as the target weight is reached. This intelligent control system significantly improves dosing accuracy, efficiency, and overall productivity.

Optimized for Challenging Powders
For sticky or cohesive products, the dosing head can be equipped with a bridge-breaker system to maintain continuous product flow, ensuring reliability across diverse applications.
