Bottling valve

[Grease05]

The bottling valves I have( one from maple retailer, leaks and ball valve drips after you shut it off for a bit) all leak. What one is recommended ?

[The dairy farmer]

is it leaking from the inside or from the threads ? if its leaking inside take it back cause it has a bad seal

The threads are not leaking, the no drip valve I had apart and made sure the taper inside was clean and not scratched, all looked good. Still leaked
