I suppose you speak English so in order to pronounce Delvaux, just say Dell (like the computer brand). Now for the second part just like you say low but instead of the "L" in low use a "V" so the second part is like saying vow (remember in the context of low not in the context of the word you pronounce in 'to make a vow'), now take away the "W" in this vow so there only remains vo. So there you have it , now just say this "dellvo" and that's pronouncing Delvaux.
Delvaux is pronounced as "del-VOH."
