Is the flange surface of the ammonia valve only concave?
Thread Content
Experts, are the flange surfaces of ammonia stop valves available only in the concave format? If the end of the reactor is convex, wouldn’t a short circuit be needed in order to connect it? ?
It’s necessary to mention what the pressure threshold for the stop valve is; if it’s at atmospheric pressure, it isn’t necessarily of the FM type.
There are those with an RF surface too; it depends on the pressure.
Liquid ammonia and ammonia gas require flange sealing surfaces with male and female profiles; if a valve with a female profile is purchased, a flange with a male profile must be used, and an adapter is needed if they do not match.
