Air valve
One more part I need to find for building a submarine. I need 2 valves to control air flow. One to let air in from a pressurized tank and one to let air out so water can flow in. People keep mentioning sprinkler valves, but I can't find any that will work for air at the local Home depot. We disected them. They have a bladder that is controlled by a solenoid. As the bladder fills, it cuts off water flow. It is very slow and will leak air. Is there something elsewhere that will work that I missed? Maybe an input valve off an old washing machine?
