Quick Exhaust Valve (QEV)

The QEV is the heart of the air cannon: when the solenoid triggers, the quick exhaust valve dumps the tank’s stored air in milliseconds — that instant release is the blast that breaks the buildup. A worn QEV means slow discharge, weak blasts, and cannons that hiss instead of fire.

If your cannons have lost their punch, this is the first part to check — and the most common one we replace on service calls.

Key Features:

• Restores full blast force: Fresh valve, full-speed discharge, buildup actually breaks.
• The #1 air cannon wear part: Diaphragms and seats wear with every firing cycle.
• Quick swap: Replaces in place during a routine service visit — or add it to our next air cannon service.
• Fits Flash Cannon systems: Confirm your cannon model in the quote and we’ll verify fit.
