Hydrogenation high pressure valve performance
Thread Content
Domestic high-pressure hydrogenation high-pressure valves mostly use VELAN and EDWARD. Has anyone compared the process performance Cv values of the two valves?
Edward's high-pressure valves have two CV value options under the same engineering diameter specification, so when buying valves from them, it is best to ask for the CV value. If not, they will provide you with the one with the smaller CV value. The CV value of the Weyland valve is between the two CV values of Edward, but there are many fake Weyland valves.
