Valve designation
Valve designation
(OP)
I am new to valves and their designation .
eg . 1" threaded Ball valve with locking device and nace trim will be 1"BCN1.LN
I understand all the letters except for the number 1 in the middle . Sometime I see 1"BCN2.LN . So what does 1 and 2 means and how to determine that when designating a valve .
Second question is about L and N . When to use a locking device on a valve and nace trim ?
Thanks

RE: Valve designation
For the most part I would contact the supplier and get their catalogs as suggested by Mike. In terms of when to go with locking device and when to go with nace trim ask the supplier as well. No one will know the product better than the manufacturer.
