Nope, neither my current nor past civic VX has a valve down there and both cars are very much stock, it's really hard to get to that lower hose unless you have help from someone with small hands, but on my first VX I took both hoses out and replaced them, along with the lower straight joint and the grommet all with parts from the dealership because that grommet over time dries out and causes the idle to bounce up and down.
Auto part stores will sell you generic parts that do have a check valve in them but the dealership does not and there is no need to replace those hallow joints because there is nothing inside of them to wear out or brake.
