Vacuum Valves and fittings

Vacuum valves are valves used to control and regulate the flow of gas in vacuum systems. They maintain and control the vacuum environment by switching, regulating or isolating the air flow within the vacuum chamber.

Common vacuum valve types include:
● Isolation valve: Used to completely shut off air flow to a vacuum system.
● Regulating valve: used to precisely control gas flow and pressure.
● Check valve: Allows gas to flow in one direction only, preventing backflow.
● Safety valve: automatically releases pressure when the system pressure exceeds the set value.

Vacuum valves are widely used in the following fields:
● Semiconductor manufacturing: Control and maintain the high vacuum environment required during production processes.
● Scientific research experiments: Vacuum experimental equipment used in the fields of physics, chemistry and biology.
● Pharmaceutical and Medical: Maintaining sterile and low-pressure environments in pharmaceutical manufacturing and medical equipment.
● Food packaging: used in vacuum packaging systems to extend the shelf life of food.

When selecting a vacuum valve, the following factors should be considered:
● Working Pressure and Vacuum Level: Ensure the valve can withstand the system's working pressure and vacuum levels.
● Material compatibility: Valve materials should be resistant to chemical corrosion and physical abrasion in the working environment.
● Valve size and connections: ensure compatibility with pipes and fittings in the system.
● Operation mode: manual, electric or pneumatic control, choose the appropriate operation mode according to the application requirements.

Common types of vacuum accessories include:
● Flanges and joints: used to connect vacuum pipes and components. Common types include ISO-KF, ISO-K, CF, etc.
● Seals: such as O-rings and gaskets, used to ensure the airtightness of the system.
●Pipeline: used to transmit gas, made of metal, plastic, etc.
● Brackets and clamps: used to secure and support components in the vacuum system.

Recommendations for maintaining and servicing vacuum valves and accessories include:
● Regular inspection: Check valves and fittings regularly for wear and leakage.
● Cleaning: Keep valves and accessories clean to prevent contaminants from affecting system performance.
● Lubrication: Regularly lubricate parts that require lubrication to ensure smooth operation.
● Replacement: Replace damaged or aging components in a timely manner to ensure system reliability.
