Split function usage in perl

I am new to perl, started learning few weeks before. I was using split function to split the $line by '|' and i want to check the protein name which is $val[2] after spliting! when I print its giving correct element but when I use it in if statement, even the given condition is false its giving yes. Pls tell me whats the mistake

#!/usr/bin/perl

$line = ">sp|P01011|AACT_HUMAN| Alpha-1:-antichymotrypsin: OS=Homo sapiens GN=SERPINA3 PE=1 SV=2";

my @val = split(/\|/, $line);

print " $val[2]\n";

if($val[2] == 'gh')

{

print " \n yes\n";

}

else

{

print "no";

}
