Laminar’s butterfly dampers provide a simple, cost-effective duct control and isolation method with various sealing options.

Available in standard sizes, our Butterfly Dampers can be manufactured in carbon steel or stainless steel, with other metals and alloys available on request or for special applications.

Laminar butterfly dampers can be actuated pneumatically, electrically or manually via a simple hand lever, gearbox, or hand wheel.

Key Features:

  • Minimal leakage through robust design and manufacturing.
  • Pneumatic, electric or manual operation choices.
  • Can be customised to suit your requirements.

Industries widely use butterfly valves due to their versatility and wide range of applications. One can operate these valves manually, pneumatically, or electrically, offering flexibility in precise fluid or gas flow control. Hence, they are ideal for systems requiring frequent adjustments.

A butterfly damper regulates air or gas flow in ventilation systems. HVAC systems and industrial exhausts often use them where temperature control is critical. Butterfly dampers provide reliable operation in demanding environments, as operators can actuate them manually or pneumatically.

Although the valve and damper share design similarities – featuring a rotating disc within a pipe – their specific functions set them apart. The butterfly valve excels at controlling fluid flow across various applications. In contrast, the butterfly damper focuses on managing air or gas flow with precision in temperature-sensitive environments.
