Which type of valve can seal at higher pressures?

The ball valve is known for its ability to seal effectively at higher pressures due to its design. In a ball valve, a spherical disc (the ball) controls the flow of fluid through it. When the ball is rotated so that the hole through it is aligned with the flow, the valve is open; when it is rotated perpendicular to the flow, the valve is closed.

The sealing surface of the ball valve is typically very smooth and, when closed, it provides a tight seal against the valve seat. This design minimizes leakage and allows the ball valve to maintain its integrity under high-pressure conditions, making it suitable for applications where pressure fluctuations can occur.

Furthermore, ball valves can handle a variety of fluid types and are highly durable, which also contributes to their effectiveness in high-pressure situations. Their quick quarter-turn operation and reliable sealing capability are advantageous features that often make them the preferred choice in many industrial applications involving high-pressure scenarios.
