Building a new air cannon with a quick exhaust valve. The solenoid has an exhaust port of 1/8". Cannon fires sometimes but mostly blows air out through the solenoid exhaust port when firing. I thought I read somewhere where the exhaust port needs to be large enough so the diaphragm will move quickly enough to shoot air out through the valve properly. Is that right? Will 1/4" exhaust on the solenoid be big enough or do I need to go larger?
