KF40 Ultra High Vacuum Valves Electric Pneumatic Vacuum Valve DQ-J40B Model

High Vacuum Baffle Valve, Block Valve 40mm, Pneumatic Drive GDQ-J40(B)

Structural Features:

• Standardized, modular design, easy to replace and repair;
• Easy to clean and dust-proof design;

Applications:

This valve is suitable for use with air and non-corrosive gases as the working medium.

It is used to cut off or connect the important components of the vacuum pipe.

Widely used in chemical, light industry, metallurgy, petroleum, machinery, electronics, and other industries

• Flow control: They are used to precisely control the flow of gases or vapors within the vacuum system. By adjusting the opening degree of the valve, the amount of gas flowing through the pipeline can be regulated, which is crucial for maintaining the desired vacuum level and process conditions.
• Isolation: Vacuum angle valves can isolate different parts of the vacuum system. This allows for maintenance, repair, or modification of specific components without affecting the entire system. For example, when a certain vacuum chamber needs to be serviced, the valve can be closed to separate it from the rest of the system, keeping the vacuum in other parts intact.
• Prevention of back-flow: They prevent the back-flow of gases or contaminants into the vacuum system. In some processes, it is essential to avoid the entry of external gases or impurities that could affect the vacuum quality or contaminate the process. The valve acts as a one-way barrier, ensuring that the flow is only in the desired direction.
• Pressure regulation: Vacuum angle valves assist in regulating the pressure within the vacuum system. They can be used to control the rate at which the pressure changes, either during the evacuation process or when maintaining a specific pressure setpoint. This is particularly important in applications where precise pressure control is required, such as in thin-film deposition or semiconductor manufacturing.
