  Drop-Through Rotary Airlock Valves

  NES Drop-Through Rotary Airlock Valves ensure precise material flow in pneumatic conveying and metering applications. Featuring a drop-through design, they allow gravity-assisted discharge while maintaining system pressure and preventing air loss. Available in cast iron or stainless steel (304/316) with 6” to 18” [150 mm to 450 mm] bore sizes, they support up to 15 psi differential pressure and 482°F [250°C] operating conditions, making them ideal for food, chemical, pharmaceutical, plastics, and bulk material handling industries.
