Hi,

val = {{{V -> 26.5173}, {V -> 340.686}, {V -> 191821.}}, {{V -> 
      26.6798}, {V -> 326.358}, {V -> 135843.}}, {{V -> 
      26.8489}, {V -> 312.824}, {V -> 98061.}}, {{V -> 27.0252}, {V ->
       300.031}, {V -> 72039.1}}, {{V -> 27.209}, {V -> 
      287.932}, {V -> 53792.5}}, {{V -> 27.4009}, {V -> 
      276.484}, {V -> 40774.4}}, {{V -> 27.6013}, {V -> 
      265.647}, {V -> 31339.2}}, {{V -> 27.8109}, {V -> 
      255.384}, {V -> 24398.6}}, {{V -> 28.0302}, {V -> 
      245.661}, {V -> 19221.5}}, {{V -> 28.26}, {V -> 236.446}, {V -> 
      15312.4}}, {{V -> 28.501}, {V -> 227.71}, {V -> 
      12322.2}}, {{V -> 28.754}, {V -> 219.424}, {V -> 10009.8}}};
val /. {V -> x_} -> {x}

should do what you want.
