Understanding vacuum valves and their importance in industrial vacuum systems
Vacuum valves are components that are essential in a variety of industrial and research applications. They play an important role in creating and maintaining vacuum conditions. These valves, ranging from simple manual valves to complex automated systems, ensure precise control over the vacuum environment, essential for processes in industries like pharmaceuticals, food, cosmetics, and more. Let’s delve into the workings of vacuum valves and understand their significance.

Understanding the vacuum valves first
A vacuum valve is a critical device that regulates the flow of gases or liquids in a vacuum system, integral to the vacuum chamber’s functionality. It’s designed to isolate and protect the system from atmospheric pressure while facilitating controlled conductance. The valve’s material, design, and seal types greatly influence its performance under various vacuum conditions. In these systems, vacuum valves are essential in maintaining stability and efficiency, ensuring that vacuum conditions are precisely maintained for applications ranging from scientific research to industrial manufacturing. By controlling exposure to atmospheric pressures and enabling exact vacuum modulation, these valves are indispensable in maintaining the integrity and functionality of the entire vacuum system.
Key components and functions
- Valve body: The main structure of the valve, often made from materials like stainless steel or aluminum alloys for durability and corrosion resistance.
- Valve seat and actuator: These parts work together to open or close the valve, controlling the flow within the vacuum system.
- Seals: From elastomer seals to more specialized options, the sealing mechanism ensures a tight closure, preventing air ingress that could disrupt vacuum conditions.
Conductance and flow control
Conductance in a vacuum valve refers to its ability to allow gas flow. Different types like butterfly valves or gate valves offer varying levels of conductance, suitable for different applications. Understanding the range of sizes and types of vacuum valves helps in selecting the right valve for specific vacuum applications.

Applications and Industries
Vacuum valves find extensive use in diverse industries, each with specific requirements. In the mentioned industries below, vacuum valves are primarily used to control and maintain vacuum conditions, rather than directly handling materials. For example:
- Pharmaceuticals: They’re essential in creating sterile environments and controlling pressure, essential for processes like lyophilization or sterile packaging.
- Chemicals: Vacuum valves play a role in safe containment and transfer of hazardous materials, often in processes requiring controlled atmospheres.
- Food and cosmetics: Here, they help maintain hygienic conditions, crucial in processes like vacuum packing or in maintaining cleanroom standards.
While these valves are vital in these sectors, their role is focused on managing vacuum conditions for process integrity and safety.
Vacuum valves vs. Ball segment valves
Vacuum- and ball segment valves serve different functions and are designed for distinct purposes:
- Vacuum valves: These valves are used to control gas flow within vacuum systems. Their primary function is to maintain and regulate vacuum conditions in a system, which is crucial in processes like semiconductor manufacturing, scientific research, and any application where a controlled vacuum environment is needed. They are not designed for handling solids but for controlling the pressure and flow of gases.
- Ball segment valves: Ball segment valves, on the other hand, are designed primarily for handling solids, particularly in industries like pharmaceuticals, food, and chemicals. They have a segmented spherical disc, which is fully shut-off by means of an inflatable seal that ensures 100% tightness and allows for precise control of material flow. They are known for their ability to handle abrasive or corrosive materials and are used in processes where there’s a need to control the flow of solid materials.
In essence, the key difference lies in their application: ball segment valves for solid material flow control, and vacuum valves for gas flow regulation in vacuum environments.

The Techno-G Ball Segment Valve (BSV) is a versatile solution for pharmaceutical and fine chemical processes, handling a variety of solids. Ideal for vacuum dryers, reactors, and centrifuges, it serves as both an inlet and discharge valve. It handles non-free flowing, abrasive, or moist and adhesive products, providing a vacuum and pressure- tight seal. Its cGMP-compliant, corner-free design allows the ball segment to move clear of the product flow path when opened. The design minimizes dead-space in the process area and can be customized with non-DIN flange connections for most reactor vessels.
