Are poppet valves or solenoids better?
Depending on the ship in question, one type of valve may be better than the other. A solenoid type valve seams to have slightly higher fire rates, and may give slightly more power. However, the price is increased weight, and a relatively complicated electrical system. Solenoid valves are best used on on large ships that have extra weight to use, and need multiple firing cannons. Such as most class 5 ships and larger. On more weight challenged ships, the weight saved from lighter valves can be used for more necessary things like batteries, and CO2 systems. Most class 4 and smaller ships should be using poppets.
