 Of course not. Take the $2$-adic and $3$-adic valuations on the rationals. The intersection of their rings is the ring of numbers with neither a $2$ nor a $3$ in the denominator, which is not a valuation ring. – Will Sawin Jan 19 2012 at 5:28
If you want more details you should probably ask at one of the sites listed in the FAQ. – S. Carnahan♦ Jan 19 2012 at 9:19
