The Schmidt Auto Air Valve Spring (Part # 2123‑107‑24) is a durable replacement spring engineered specifically for Schmidt 1¼″ and 1½″ regular-flow Auto Air Valves (AAVs). This essential component ensures the internal diaphragm reliably reverts to its closed position after pressurization cycles, maintaining rapid, leak-free valve operation. Constructed from industrial-grade spring steel, it withstands repetitive use in abrasive blasting systems and helps prevent valve sticking or failure. Ideal for maintenance professionals seeking quick, reliable spare parts to minimize downtime.
