Frequently Asked Questions

Is this valve a direct physical replacement for my existing Tetra Pak rotary valve?

Yes, the Doebritz rotary valve is specifically engineered as a direct drop-in replacement. It is designed to match standard flange dimensions (DIN/ANSI) and inlet/outlet configurations of common Tetra Pak powder valve models, simplifying the retrofitting process without requiring major pipeline modifications.

What materials are available for the valve housing and rotor?

Standard construction uses premium Cast Iron (GG25) or Stainless Steel (304 and 316L). For highly abrasive or specialized applications, we offer options such as Ni-Hard, Stellite hard-facing, and specific surface coatings to maximize wear life.

How does the Doebritz valve ensure minimal air leakage?

Our valves are machined to extremely tight clearances using state-of-the-art 5-axis CNC equipment, typically between 0.10mm and 0.15mm. Additionally, we offer outboard bearing and shaft seal configurations with air-purge lantern rings to prevent material ingress and further ensure an airtight seal.

Is this product ATEX certified?

Absolutely. The Doebritz replacement valve is available with full ATEX certification for use in potentially explosive atmospheres (Zone 20, 21, and 22), ensuring compliance with stringent international safety standards for industrial powder handling.

What is the typical lead time for this valve?

As a manufacturer, Doebritz maintains a strategic inventory of raw materials and semi-finished components to offer rapid deployment. Standard lead times are typically 4-6 weeks, with expedited options available for critical breakdown situations. Please contact our sales team to discuss your specific delivery requirements.
