This series of valves are core control components for central air conditioning, ventilation, and fire smoke exhaust systems. They are used to regulate airflow, open and close airflow, control fire and smoke exhaust, and control pressure, ensuring the safe, stable, and efficient operation of the system. These products are widely used in ventilation projects in commercial buildings, factories, hospitals, shopping malls, hotels, underground parking garages, and other buildings.

1. Airflow Regulating Valve (Manual/Electric)

   Function: Regulates the airflow in the duct, balances system air pressure, and controls the supply air, return air, and fresh air volume. Features: Good blade sealing, smooth adjustment, low resistance, and stable operation; can be manually adjusted or remotely controlled with an electric actuator. Applications: Central air conditioning supply and return air ducts, fresh air systems, and exhaust ducts.

2. Fire Dampers/Smoke Exhaust Fire Dampers

   Function: Automatically closes/fuses to close in case of fire, blocking the spread of flames and smoke; smoke exhaust valves are used for high-temperature smoke exhaust. Features: Fire dampers automatically close at 70℃, smoke exhaust fire dampers automatically close at 280℃, complying with national fire protection standards, safe and reliable.

3. Check Valve (Non-return valve)

   Function: Prevents backflow of air, odors, and noise. Features: Simple structure, sensitive operation, no air resistance, automatic opening and closing. Applications: Exhaust ducts, fan outlets, bathroom/kitchen exhaust systems.

4. Electric Airtight Valve

   Function: Fully open/fully closed electric valve for complete sealing and shut-off of pipelines. Features: Extremely tight sealing, extremely low air leakage rate, remote automatic control. Applications: Ventilation ducts requiring strict sealing, clean rooms, laboratories, exhaust systems.

5. Pressure Relief Valve (Pressure relief valve)

   Function: Automatically maintains indoor pressure, automatically opens to relieve pressure in case of overpressure, ensuring stable pressure. Applications: High-rise building stairwells, positive pressure ventilation systems in vestibules, cleanrooms.

6. Side-by-side Multi-leaf Regulating Valve

   Function: Precise adjustment of airflow in large-area ducts, ensuring uniform airflow distribution. Features: Multi-blade synchronous adjustment, good balance, large air volume, and low noise. Applications: Large air ducts, central air conditioning main ducts, industrial ventilation.

7. Flue Check Valve / Smoke and Fire Damper

   Functions: Prevents backflow of oil fumes, fire prevention, and odor control. Applications: Kitchen exhaust, public flues, restaurant exhaust.
