Locke 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, with good wear resistance, stable and reliable work, 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. 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 air source, the switch operation can be realized, and two pairs of passive contact signals are sent to indicate the valve switch. Pneumatic ventilation regulating butterfly valve is mainly used in industrial, metallurgical, environmental protection and other pipelines for ventilation regulating medium flow.

三、進口氣動通風碟閥產品特點:

1、啟閉方便迅速、省力、流體阻力小，可以經常操作。

2、結構簡單，外形尺寸小，結構長度短，體積小，重量輕，適用于大口徑的閥門。

3、低壓下，可以實現良好的密封。

4、調節性能好。

5、全開時閥座通道有效流通面積較大，流體阻力較小。

6、啟閉力矩較小，由于轉軸兩側蝶板受介質作用基本相等，而產生轉矩的方向相反，因而啟閉較省力。

7、安裝方便。

8、操作靈活省力，可選擇手動、電動、氣動、液壓方式。

1. The opening and closing is convenient, quick, labor-saving, low fluid resistance, and can be operated frequently.

2. Simple structure, small size, short length, small volume, light weight, suitable for large caliber valves.

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

4. Good regulation performance.

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

6. The opening and closing torque is small, because the disc on both sides of the shaft is basically the same under the action of the medium, and the direction of the torque is opposite, so the opening and closing is more labor-saving.

7. Easy to install.

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