I'll give you an insight of what the Venusian Arts handbook says about it. Read it if you want more.
Value is the short term for Survival&Replication Value. According to Mystery, women tend to be attracted to a guy for 80% based on survival value (your actions) and for 20% on replication value (looks).
So, one way to DHV is to be good looking. Notice that good looks will only help you in situations (gives you a headstart), bad looks will never work against you.
Another way of DHVing is by showing that you are comfortable around women, by kino escalating or by hanging around with other women.
There are many more DHVs
