Product Description

　　 　　Galvanized airtight valve 　　 　　 　　 　　Usage: Mainly used for air supply valves, return valves and mixer valves in air conditioning systems with low leakage rate. Generally used for regulating air intake, exhaust and mixed air flow. It has the advantages of low leakage rate, good control performance, wide working temperature range, small friction moment and good corrosion resistance. 　　 　　 　　 　　Characteristic: The outer frame of the air valve is formed by folding and exaggerating 2 mm thick and high quality galvanized iron plate, which can punch the flange installation holes in advance for users. The blade is made of double layer 1.0mm high quality galvanized iron sheet and butted by spot welding. It has high strength, high static pressure resistance and high wind speed. There are general type, heat-resistant type, thermal insulation type, for users to choose. Special material and type of sealing structure are adopted to ensure that the blades are sealed reliably and leakage is low when the air valve is fully closed. The bearing adopts oil sintered bronze bearing with low friction, long service life and no maintenance. 　　 　　 　　 　　Aluminum alloy regulating valve 　　 　　 　　 　　Characteristics: Aluminum alloy with high strength surface and anodized. The blade and the blade, the blade and the outer frame are sealed with seals. The manual type can be adjusted in six grades in the range of 0-90 degrees, and the electric type can stop at any angle. Type FK-LM1 rotates with gears and is hidden in the frame to avoid dust accumulation and damage. FK-LM2 adopts connecting rod rotation and connecting rod cover plate to prevent dust accumulation and damage. 　　 　　 　　 　　Aluminum alloy airtight valve 　　 　　 　　 　　Characteristic: Made of couple alloy with high strength surface by anodic oxidation. Blade and blade. Both blade and outer frame are sealed with seals. The manual type can be adjusted in six grades in the range of 0-90 degrees, and the electric type can stop at any angle. Type FK-LM1 rotates with gears and is hidden in the frame to avoid dust accumulation and damage. F K-LM2 adopts con
