进口气动通风碟阀产品特点：

1、启闭方便迅速、省力、流体阻力小，可以经常操作。

2、结构简单，外形尺寸小，结构长度短，体积小，重量轻，适用于大口径的阀门。

3、低压下，可以实现良好的密封。

4、调节性能好。

5、全开时阀座通道有效流通面积较大，流体阻力较小。

6、启闭力矩较小，由于转轴两侧蝶板受介质作用基本相等，而产生转矩的方向相反，因而启闭较省力。

7、安装方便。

8、操作灵活省力，可选择手动、电动、气动、液压方式。

Introduction of imported pneumatic ventilation butterfly valve products:

The imported pneumatic ventilation butterfly valve is widely used in the ventilation and dust removal system. It is used for flow regulation and closure of dusty gas, gas pipeline, ventilation and purification device, flue gas pipeline, etc. The pneumatic ventilation butterfly valve is welded with high-quality wear-resistant materials. It has good wear resistance, stable and reliable operation, convenient operation, sensitive action, small leakage rate, long service life and convenient installation and maintenance. The 641w pneumatic ventilation butterfly valve is especially suitable for low pressure difference, large diameter and large flow occasions. It is combined with various actuators to form valves with different performance. The pneumatic ventilation regulating butterfly valve is matched with the electric valve positioner, and the operation can be controlled by inputting 4 ~ 20mADC signal and 0.4 ~ 0.7MPa air source to realize the adjustment of pressure, flow, temperature, liquid level and other parameters. Or equipped with travel limit switch, solenoid valve, pressure reducing valve and 0.4-0.7mpa gas source, the switch operation can be realized, and two pairs of passive contact signals are sent to indicate the switch of the valve. Pneumatic ventilation regulating butterfly valve is mainly used in industrial, metallurgical, environmental protection and other pipelines to regulate the medium flow.

Features of imported pneumatic ventilation butterfly valve:

1. It is easy to open and close, labor-saving, low fluid resistance, and can be operated frequently.

2. Simple structure, small size, short structure length, small volume, light weight, suitable for large diameter valve.

3. Under low pressure, good sealing can be achieved.

4. Good regulation performance.

5. When the valve seat channel is fully open, the effective flow area is larger and the fluid resistance is smaller.

6. The opening and closing torque is small, because the butterfly plates on both sides of the shaft are almost equal to the medium, and the direction of the torque is opposite, so the opening and closing is less labor.

7. Easy to install.

8. The operation is flexible and labor-saving, and manual, electric, pneumatic and hydraulic modes can be selected.

Performance range of inlet pneumatic ventilation butterfly valve:

Nominal diameter DN50-DN2000

working pressure 0.25Mpa-0.6Mpa

working temperature - 40+425℃

Driving mode Manual, pneumatic, electric

Connection mode Flange type

Manufacturing standards GB, JB, Hg, API, ANSI, BS, JIS, JPI, etc

body material Cast iron, cast steel, carbon steel, WCB, stainless steel, 304, 304L, 316, 316L, etc
