air compressor check valve install help

[sweetk30]

in tank from top style found on most setups like this http://www.ebay.com/itm/201161641035?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT

can it be installed in the side of a tank ?

reason I ask is this model specifies vertical or horizontal install http://www.ebay.com/itm/190676680167?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT

thanks for the help guys.
