Frequently Asked Questions

For the most accurate quote please provide the following information:

• Type or style of damper. For example: butterfly, louver, Tee, diverter, etc.
• Preferred material, such as stainless steel, carbon steel, other
• Pressure requirement

Compact design, most economical, no exterior linkage, higher shutoff rates and butterfly dampers remain consistent along temperature swings.
