Solenoid valve troubles

[Gibbs]

My team is just getting over our long held fear of Pneumatics, and we seem to be having trouble with the Solenoids specifically the Solenoid valve VUVG-L10-B52-T-m7-1P3-566475. If someone could possibly give us pointers on how to use it, or point us towards a resource for help that would be much appreciated. One of the things we couldn't figure out was which end is the intake, and which end is exhaust. Also our lead programmer says that the solenoid was taking approximately ten seconds to respond to commands.

Thanks!
