While it is commonly held that veins in the "Triangle of Death/Danger" do not have valves, this reference from the page
Danger triangle of the face,
indicates that these veins do generally have valves, and appears to provide other reasons for why this is a dangerous region of the face.
I suggest the article be edited to remove the statement about these veins not having valves. Smedley7 ( talk) 07:56, 16 February 2017 (UTC)
