Powder Dosing Valves with Bridge Breaker – Composite & Rotary | HD Process

Oyster composite and rotary powder dosing valves deliver high precision discharge and volumetric dosing of powders, making them ideal for pack‑off systems. Optimised design helps achieve efficient filling protocols and consistent dosing accuracy.

The composite valve pairs a butterfly main leaf with a miniature dosing head to dispense tiny amounts of product during fine dosing. A 4–20 mA positioner enables proportional closing as the target weight is approached, boosting productivity. For sticky powders, a bridge breaker agitator keeps product flowing. Rotary dosing valves offer lower pressure drop for free‑flow powders. All valves are built to cGMP standards with smart geometry to eliminate recesses and are finished to the highest pharmaceutical standards.
