This multi-blade adjustable gate valve is commonly used in air conditioning and ventilation system pipelines to regulate the air volume of branch pipes, and can also be used for mixing fresh air and return air adjustments.

I. Product Features

1. This regulating valve has the same pipe size as the rectangular duct dimensions specified in the national ventilation pipeline standardization regulations.

2. The regulating valve blades are of the opposed type, serving as regulating valves in ventilation, air conditioning, and air purification systems, and are superior to valves of the parallel design.

II. Structural Characteristics

1. This regulating valve features uniform blade widths in four standard sizes, with diamond-shaped single blades. Double blades can also be custom made.

2. The assembly between the blade shaft and the frame uses copper bushes, ensuring lightness, flexibility, and stability, while preventing partial jamming.

3. The regulating valve is available in manual and electric (220V, 24V) options. It is categorized by material used: carbon steel plate, galvanized plate, and stainless steel plate. The valve body structure and specifications are identical.

4. Hand-operated and electrically operated multi-leaf regulating valves can both be customized as insulated types according to customer requirements.

5. Our factory's sealed air volume regulating valves have excellent air tightness, with a relative air leakage rate of around 0.5%, in compliance with relevant regulations.
