Butterfly valve (mainly composed of valve body, valve stem, butterfly plate and sealing ring) is a simple regulating valve, and it can also be used for on-off control of low-pressure pipeline media. Ventilation butterfly valve is a non-closed butterfly valve. Ventilation butterfly valves are used in dusty cold air or hot air gas pipelines of ventilation and environmental protection projects in chemical, building materials, power stations, glass and other industries, as a gas medium to adjust the flow (unit: cubic meters per second) or cut off the pipeline control device. This type of valve should generally be installed horizontally in the pipeline.

(1) The air volume control valve has four specifications when the blade width is all the same. The blade shape is a diamond-shaped double blade, and the blades are soft overlapped, so the sealing performance is excellent.

(2) The valve body frame of the air volume control valve is injection molded from polypropylene material, which has good sealing performance. The product itself has the characteristics of anti-acid and alkali corrosion, and can be widely used in exhaust gas exhaust pipes.

(6) The dispatch valve is divided into manual and electric. The valve body structure and specifications are the same.

The current manual air valve mold a molding, high strength, good sealing, smooth appearance, low resistance. Its specifications are diameter 63 mm, 75 mm, 90 mm, 110 mm, 160 mm, 200 mm, 250 mm, 315 mm. The diameter of this pneumatic equipment is more than 357 mm which can be customized.

Adopt the new series of GT electric actuators, with double-acting and single-acting (spring reset), gear transmission, safe and reliable; large-diameter valves adopt series AW-type pneumatic actuators with fork drive, reasonable structure, and ample output torque. There are double-acting and single-acting.

1. Geared double pistons, ample output torque, and small volume.

2. The cylinder is made of aluminum gold material, which is light in weight and beautiful in appearance.

3. Manual operating mechanism can be installed on the top and bottom.

4. The rack-and-pinion connection can adjust the opening angle and rated flow.

5. The actuator can be equipped with electrical signal feedback instructions and various accessories to realize automatic operation.

6. IS05211 standard connection provides convenience for product installation and replacement.

7. The joint screws adjusted at both ends can make the standard product have an adjustable range of ??4?? between 0?? and 91??. Ensure the synchronization accuracy with the valve.
