Sanitary Rotary Valve – High Hygiene Powder Handling Solution for Food, Pharma & Chemical Industries

Introduction to Sanitary Rotary Valves

A sanitary rotary valve is a critical component in modern powder handling systems, designed for controlled feeding, discharge, and airlock applications in hygienic environments. In industries such as food processing, pharmaceuticals, dairy, and chemicals, contamination control and cleanability are essential requirements.

The sanitary rotary valve solutions from Doebritz Tec are engineered to meet strict international hygiene standards, including EHEDG, USDA, and FDA material compliance, ensuring safe and reliable bulk material processing.

What Is a Sanitary Rotary Valve?

A sanitary rotary valve is a precision dosing device used to regulate the flow of powders, granules, and bulk solids between different process stages.

Typical functions include:

• Airlock sealing in pneumatic conveying systems
• Controlled powder feeding and metering
• Preventing pressure loss between process zones
• Ensuring dust-free material transfer

According to industrial standards, product-contact parts are commonly made from AISI 304 or AISI 316 stainless steel, ensuring corrosion resistance and hygienic performance in sensitive applications.
