Valves for anhydrous ammonia service
Valves for anhydrous ammonia service
(OP)
What is a good, basic isolation valve for anhydrous ammonia service, not refrigerated storage. We currently have SS gate valves, 2" and 3" 300# class that are not sealing well at all under nitrogen pressure testing. Is a gate valves appropriate for this service?, metal to metal ball valves or soft seat ball valves?

They did have a very good brochure on NH3.
The second site has some very good physical data on NH3.
