The electric air control valve is used as a gas medium to adjust the flow or cut off the dust in the dusty cold air or hot air gas pipeline of the ventilation and environmental protection projects in the hardware, chemical, building materials, power station, glass, waste gas treatment, and other industries.

The electric air volume control valve is composed of an electric actuator and a valve body. An electric butterfly valve is usually composed of a quarter-stroke electric actuator (0~90° partial rotation) and the butterfly valve as a whole through mechanical connection. The active mode is classified into the on-off type and regulating type, and the latter two. Generally, a straight thread electric actuator (0~100) is mechanically connected to the valve body.

Features of electric air volume control valve

1. It is designed and manufactured by adopting a new structural form of welding of mid-line disc plate and temporary structure steel plate. It has a compact structure, lightweight, easy installation, low flow resistance, large circulation, avoids the influence of high-temperature expansion, and is easy to operate.

2. There are no connecting rods, bolts, etc., so it works reliably and has a long service life. It can be installed in multiple positions and is not affected by the flow of the medium.


This butterfly valve is a non-closed butterfly valve, which is widely used in the production process of building materials, metallurgy, mining, electric power, and other production processes on pipelines with a medium temperature of ≤300℃ and a nominal pressure of 0.1Mpa to communicate, open and close or adjust the amount of medium.

Structural features:

This butterfly valve is designed and manufactured by adopting a new type of structure welded between a centerline disc plate and a temporary structure steel plate. It is compact in format, light in weight, easy to install, small in flow resistance, large inflow, and easy to operate. There are no connecting rods, bolts, etc., in the body, reliable work, and long service life. It can be installed in multiple positions and is not affected by the flow of the medium.

working principle:

The butterfly valve is driven by a motor to go to the actuator so that the disc can rotate freely within the range of 90° to achieve the purpose of opening and closing or adjusting the flow of the medium.

Uses and characteristics of electric air volume control valve

This valve is made of the same material as the valve body and processed into a sealing ring, which adopts electric or pneumatic transmission. The applicable temperature depends on the material selection of the valve body, and the nominal pressure is ≤0.6MPa. Generally, it is suitable for industrial, metallurgical, environmental protection, and other pipelines for ventilation and media flow adjustment. Its main features are:

1. Novel and sound design, unique structure, lightweight, and rapid opening and closing.

2. Small operating torque, convenient operation, labor-saving and dexterous.

3. Use suitable materials to meet the requirements of low, medium and high medium temperatures and corrosive mediums.

Electric air volume control valve adopts standard

Design standard: GB/T12238-1989 JB/T8692-1998

Flange connection size: GB/T9115.1-2000

Structure length h: GB/T12221-1989

Pressure test: GB/T13927-1992; JB/T9092-1999

Electric air volume control valve actuator

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 90°. Ensure the synchronization accuracy with the valve.
