Visa renewal in case of no travel till the expiry of first stamping validity date

My H1b Visa stamping was done in Nov 2016 valid till Sep 2017.In case i do not travel till Sept 2017 due to non availability of roles, can the visa be renewed again to travel to US.

you need to have an approved and valid H1 petition (I-797) at the time of stamping(even first or renewal stamping, doesnt matter)

Thank you for the quick response
