How to choose a root valve for high-temperature instruments?
Thread Content
How should one choose a root valve for high-temperature pressure transmitters with a medium temperature of 980 degrees? Where can one find such valves? Which are the manufacturers of imported instrument tubing and valve components?
There are still quite a number of manufacturers of root valves for instruments under high-temperature conditions used in power plants built in China.
It’s a pressure transmitter, right? The root valve isn’t a problem; ordinary two-valve assemblies or sampling isolation valves will generally suffice. However, for the pressure transmitter, the temperature is a bit high, so a condensation elbow needs to be added.
