The proportion of valves used in chemical plants in the total project investment and the number of imported valves
Thread Content
I would like to ask the experts here: what proportion do valves account for in the total investment of chemical projects? Approximately how many valves are there in total, and what is the typical number of imported valves? Thank you!
Process valves account for roughly 5%-10%. I’m not familiar with control valves; the proportion of such valves varies depending on the equipment, and it also differs for imported products. Apart from those operating under high temperature and pressure or in special conditions, the proportion of imported devices is relatively low at present; the specific import ratio depends on the type of device
