真空閥門也可以分為手動真空閥門，氣動真空閥門，電動真空閥門。 而真空閥門和普通壓力閥門的卻別在于，真空閥門是用于隔離(切斷)氣流、調節氣流和分配氣流。各種真空裝置(又稱真空工程設備)都離不開真空系統。真空閥門在簡單或復雜的真空系統中起著重要的作用。

現在我們能夠應用的真空閥門的類別非常的多，根據不同的需要我們可以選擇不同結構的閥門，例如真空球閥、真空蝶閥、真空擋板閥、真空插板閥、真空隔膜閥等。畢竟現在各類不同結構的真空閥門具有各自不同的用途，選擇在合適的環境使用合適的真空閥門，才能夠真正的發揮它的效果。

Classification of Vacuum Valves

Vacuum valves are divided into manual vacuum valves, pneumatic vacuum valves, electric vacuum valves. The difference of vacuum valves and ordinary valves, that vacuum valve is used to isolate (cut off) the flow of air, regulate the flow and distribution of air. All kinds of vacuum devices (also known as vacuum engineering equipment) are inseparable from the vacuum system. Vacuum valves play an important role in simple or complex vacuum systems.

Now we can apply a lot of categories of vacuum valves, according to different needs we can choose different structures of valves, such as vacuum ball valve, vacuum butterfly valve, vacuum flapper valve, vacuum gate valve, vacuum diaphragm valve and so on. After all, now all kinds of different structures of vacuum valves have their own different uses, choose to use the right vacuum valve in the right environment, can really play its effect.
