Rotary valve
InoxFlow sanitary rotary valves deliver airlock-tight, batch discharge of powders and granules for food, beverage, pharmaceutical, nutraceutical, and chemical processing. Each valve is precision-machined from solid stainless steel — never cast — eliminating the internal porosity that traps product and harbors bacteria, for smoother surfaces, easier cleaning, and longer service life under continuous duty.
Airlock Batch Discharge
The rotary valve meters powder in controlled batches as the rotor turns, maintaining a pressure seal between inlet and outlet. That airlock action makes it ideal for dosing, batching, and feeding into pneumatic conveying lines — anywhere you need a measured, repeatable discharge without losing pressure across the valve.
Need continuous rather than batch flow?
See our Feeder Valve, engineered for uninterrupted, metered powder flow.
Gentle-Handling Option: SILICONE ROTOR
Roto Tab
Handling tablets, capsules, or friable granules? Opt for a gentle-handling configuration with a silicone rotor in place of stainless steel. The flexible rotor moves fragile product through the valve softly — preventing breakage, cracking, and fines — while maintaining the same reliable, airlock-tight discharge. Same trusted valve body, configured to protect what passes through it.
Machined, Not Cast
Machining from solid bar stock — instead of casting — gives every InoxFlow valve:
- No internal porosity for product or bacteria to lodge in
- Tighter tolerances for consistent, repeatable metering
- Smoother internal surfaces for faster, more thorough clean-in-place cycles
- Longer service life under repeated rotation and wash-down
Beyond Sanitary: Built to Your Application
Need a non-sanitary or specialty configuration? InoxFlow rotary valves are built to order and adapt well beyond hygienic processing — including abrasive media — through tailored material, seal, and finish selection. If you have an unusual requirement, it’s worth a conversation.

FREQUENTLY ASKED QUESTIONS
A sanitary rotary valve meters powders and granules in controlled batches while maintaining a pressure seal between inlet and outlet — used for dosing, batching, and feeding into conveying lines in hygienic processing.
A rotary valve discharges material in measured batches with an airlock seal, while a feeder valve delivers a continuous, metered flow. The right choice depends on whether your process needs batch dosing or uninterrupted feeding.
Yes. InoxFlow offers a gentle-handling configuration (Roto Tab) with a silicone rotor instead of stainless steel, moving fragile product through softly to prevent breakage while maintaining airlock-tight discharge.
Machining from solid stainless steel eliminates the internal porosity created during casting, giving smoother surfaces, easier cleaning, no harbor points for bacteria, and longer service life.
