Damper valves regulate airflow in HVAC and industrial systems. Key types include Multilouver Dampers, which control air direction with adjustable blades, Guillotine Dampers, known for quick shut-off in high-pressure lines, and Butterfly Dampers, which use a rotating disk for airflow control. These devices are made from durable materials like stainless steel or aluminum, often featuring high-quality seals and actuators. Designing involves CAD software for precision and CNC machinery for manufacturing. Theyre used in power plants, HVAC systems, and chemical industries to optimize air flow, energy efficiency, and safety. Their benefits include reduced operational costs, reliable airflow control, and improved system performance.
