Apparently some leakage is normal. From ... P47904.pdf page 70.

"Steam or Water Service –For high steam pressure and/or high capacity applications.•
Stainless Steel Double Seat and Trim – Trim consists ofseat rings and center guided plunger.
Double seated valveshave 1% allowable leakage rate. "

How much is your valve leaking?
