2、 ElectricRectangular air duct check valve manufacturerrightProduct usage:

The rectangular air duct check valve produced by our factory is widely used in ventilation pipeline systems in industries such as building materials, mining, power, light industry, and glass, for one-way airflow regulation and reverse shut-off.

3、 Electric rectangular air duct check valveInnovative structural design, flexible operation, small size, and light weight. When ventilating, it is opened by the wind pressure. When the reverse wind stops, the valve plate closes automatically due to the weight of the blades and the heavy hammer, and the air flow rate is adjusted by adjusting the position of the heavy hammer. T303P-1 air duct check valve is installed on a horizontal pipeline and connected with a circular flange, T303P-2 is connected with a flange, T303C-1 air duct check valve is installed on a vertical pipeline (without a heavy hammer) and connected with a circular flange, T303C-2 is connected with a flange.

4、 The electric rectangular air duct check valve has a novel structural design, flexible operation, small size, and light weight. When ventilating, it is opened by the wind pressure. When the reverse wind stops, the valve plate closes automatically due to the weight of the blades and the heavy hammer, and the air flow rate is adjusted by adjusting the position of the heavy hammer.

Note: Rectangular butterfly valves with large diameters of 1000 ´ 800~4000 ´ 3600 need to be equipped with worm gear transmission devices, which should be specified when ordering

5、 Product Features

Unidirectional flow control: It can accurately achieve unidirectional airflow, effectively prevent backflow, ensure the normal operation of the ventilation system, and avoid various problems caused by airflow backflow, such as pollutant backflow, odor diffusion, etc.

Easy installation and maintenance: It has a simple buckle or bolt fixing method, and the installation process is simple and fast, making it easy to install or replace in existing air duct systems. At the same time, the structure is relatively simple, easy to maintain and repair, and reduces the cost of use.

Multiple optional functions: Some rectangular air duct check valves are equipped with fire prevention functions and made of flame-retardant materials, which can prevent the spread of fire and smoke through ventilation ducts in the event of a fire, enhancing the safety of the entire ventilation system. Some check valves also have intelligent control functions that can be integrated with building management systems to achieve remote monitoring and regulation.

Low pressure loss: In the open state, the resistance to airflow is small, the pressure loss is low, and it will not excessively affect the air volume and speed of the ventilation system, ensuring the efficiency of the ventilation system.
