Hi rneill
I must say thankyou again.
I mean that what is the valve welding type, when the pipe
type is no determine.and I choose must be suitable General
situation.maybe a form such as flow:
valve class pipe type
2500lb sch160
1500lb sch80
900lb sch80
600lb...
rneill,so good,thankyou
Normally,Is that have contrast about rating and pipe type
