Question 1

Powder butterfly vs ventilation butterfly — what is the difference?

Accepted Answer

Powder butterflies focus on solids isolation at hoppers and process outlets. Ventilation butterflies are sized for air or dust-laden gas ducts with defined leakage and temperature grades. Share whether the line carries powder or gas so we select the right seat and actuator.

Question 2

What leakage can I expect on duct butterflies?

Accepted Answer

Typical catalogue figures are about ≤3% for standard builds and ≤1% for high-seal designs. Critical containment duties may need an alternative valve type — tell us your allowable leakage.
