1/2" 15mm valve CV is 5.5tuckinrim said:whats the cv of a 1/2 smc compared to the 3/8 smc. whats 3/4 line going for a foot.
what i dont get is how a npt 3/8 fitting valve side is slower than npt 3/8 fitting on bag side. would nt the flow be restricted by the id of the fitting or is it the id of the valve that is smaller than the id of the fitting?
i understand that cause i recently drilled and taped my bags from 1/4npt to 3/8npt. the dia is over a 1/2".SlammedDime said:1/2" 15mm valve CV is 5.5
3/8" 10mm valve CV is 2.4
3/4" line is about $1.50 a foot... maybe a lil more.
You aren't understand how NPT fittings work. 3/8" NPT, DOES NOT mean that the diameter of the port is 3/8". 3/8" NPT port is more like 1/2" accross. The Flow diameter of a 10mm valve is .393", and the ID of 1/2" line is .376", and the flow diameter of a 1/2" tube x 3/8" NPT fitting is .338" So the restriction of less than .06" IS NOT noticeable in any way.
If you had a 1/2" NPT fittings, and 1/2" line, the SAME NUMBERS apply, because the flow diameter is the same as the 3/8" fittings, in regards to the fittings.
