What does DV stand for?
Thread Content
What does DV represent in a general process flow diagram? A. Check valve, B. Vent valve, C. Trap, D. Balance tank
If not for the drain, if not for the vent
It’s not clear whether the answer is among your options; on our process diagrams, DV stands for density control valve
I understand it should be called a Drain Valve, a discharge valve, or a drain valve
B. Exhaust valve, low-point drain valve
We all use DR to denote drainage
