Classification Of Vacuum Valves

A vacuum valve is a vacuum system element used in a vacuum system to change the direction of the air flow, adjust the size of the air flow, and cut off or connect pipes. The vacuum valve closure is sealed with a rubber seal or metal seal.

The bellows of the bellows globe valve are made of stainless steel, high zinc brass JI80, plastic and other materials. Diaphragm seal may be used for closing globe valves of small bore sizes (calibre below 10 mm). Low and medium vacuum can be used with spherical plug valves.

A vacuum valve is a component of a vacuum system for regulating gas flow and cutting off air flow. With the development of vacuum technology, there are many kinds of valves with different materials, structures and USES.classification-of-vacuum-valves

Classification of vacuum valves:

1. According to the working pressure range, it can be divided into low, high and ultra-high vacuum valves.

2. According to the structural form, it can be divided into baffle valve, flip plate valve, butterfly valve, insert plate valve, needle valve, etc. There are also “two links”, “three links” to classify.

3. According to the transmission mode in the structure, it can be divided into manual, pneumatic, electromagnetic and hydraulic transmission, etc.

4. According to the purpose, it can be divided into globe valve, throttle valve, fine tuning valve < needle valve > and air vent valve, etc.

5. According to the material of valve body, it can be divided into metal valve and glass piston, etc.DDC_JQ_B_series_electro_magnetic_vacuum_gas_valve
