Working Principle

Understanding the working principle of our 304/316 stainless steel vacuum ball valves and stop valves is essential for their effective application in high vacuum systems. Here’s a detailed overview of how these valves operate:

• Vacuum Ball Valve: The ball valve operates by rotating a spherical disc within the valve body. When the ball is aligned with the flow path, the valve is open, allowing fluid or gas to pass through. When the ball is perpendicular to the flow path, the valve is closed, effectively sealing the passage. This design ensures quick and reliable switching, crucial for maintaining vacuum integrity.

• Vacuum Stop Valve: The stop valve operates by sliding a sealing element (usually a disc or a wedge) across the flow path. When the sealing element is positioned to block the flow, the valve is closed. This precise control mechanism is ideal for applications requiring fine adjustments and stable vacuum conditions.

• Sealing Mechanism: Both types of valves utilize advanced sealing materials such as PTFE and Viton. These materials provide exceptional sealing performance, preventing any leakage and maintaining high vacuum levels. The sealing elements are designed to withstand extreme temperatures and pressures, ensuring long-term reliability.
