Auto Air Valve – 1-1/4", Industrial Air Control Valve (Normally Closed)

Part Number: 888-2123-107PB
Weight: 8.80 lbs

The 1-1/4" Auto Air Valve (Normally Closed) is a heavy-duty industrial air control valve engineered for professional abrasive blasting systems. Designed to automatically regulate airflow and maintain safe, reliable operation, this normally closed valve prevents air from entering the blast vessel until activated—improving operator safety and system efficiency.

Built for high-flow applications, the valve features a robust construction that withstands harsh blasting environments, continuous cycling, and demanding workloads. It delivers consistent sealing performance, smooth actuation, and long service life, making it a trusted component for contractors, fabrication facilities, and industrial blasting operations.
