Rotary airlock valves are designed to continuously and precisely discharge powdered or granular products from environments with differential pressure, ensuring perfect air tightness and helping maintain system efficiency.

They are commonly used for unloading pneumatic conveying lines, installed beneath cyclone separators to transfer product without pressure loss, or fitted on bag filters for the safe evacuation of extracted dust.

Thanks to their robust construction and the option to be manufactured in various materials—such as cast iron, carbon steel, or stainless steel—our rotary valves are perfectly suited to a wide range of applications in the milling, feed, and food industries, guaranteeing reliability, long service life, and minimal maintenance.
