Solenoid as fill and bleed valve

[jason701802]

I am working on a project where I have an air supply and a tank, I want to be able to control whether air allowed to fill the tank, the supply and tank are isolated, and the air in the tank is allowed to bleed to the atmosphere. I would be able to do this with a double action solenoid that has a neutral. What I want to know is if any of the solenoids that have been given to us in the past have this feature or if there is another way to achieve this with the solenoids that we are given. I know that I can do this by connecting an additional solenoid to the exhaust of the first solenoid, but it is a poorly functioning and overcomplicated solution.
