Model: FT shipments: one million units Delivery: 1-3 days Texas damper manufacturers to supply the air flow control valve is a civil industrial plant ventilation, air conditioning and air purification project indispensable central air conditioning end accessories, general used in air conditioning, ventilation duct system, used to adjust the air flow manifold can also be used to adjust the fresh air mixed with return air. First, the air-flow characteristics of the valve (l) off more Yefeng volume control valve to take over the same size with the national standardization ventilation ducts specified rectangular duct size. (2) air flow control valve leaves off and cis-open, ventilation, air conditioning, air purification system as a regulator. (3) The test measured air volume control valve tightness good, the relative amount of air leakage around 5% regulation performance. Second, the air flow control valve structural features (l) of the air flow control valve in the unity of the whole blade width four sizes, leaf-shaped diamond-shaped double blades, vanes between soft lap, so good airtight performance. (3) air flow control valve body architecture After 2 mm cold rolled galvanized sheet molding, carbon dioxide gas welding or welding by ordinary Q235 plate processing; blades with 1 mm cold rolled galvanized sheet for corrugated, two synthetic spot-square shaft inserted, or 2 mm G235 steel cold forming, punching chip interpolating axes or welding circular shaft. (4) The valve sub-manual, electric, divided according to the materials used: iron, galvanized sheet, aluminum plate, stainless steel four, the same body structure and size specifications. Third, the air flow control valve scope widely used in mining, civil construction HVAC systems, air flow is accurately adjusted, is one of the key devices to achieve a variety of environments under control ventilation mode. Its main feature is flexible operation, low noise, small amount of leakage, (closed type leakage <0.5%) Operating temperature region wide, reliable structure, safe and convenient.
