Ball valve leakage is an issue that can disrupt the seamless flow of processes and lead to costly downtimes. Whether you’re working with flange ball valve, pneumatic ball valve, or electric ball valves, understanding how to effectively inspect, avoid, and fix leaks is crucial.
When the ball with the welding spatter is opened and closed, the valve seat will be further damaged, resulting in internal leakage. If the ball valve stem drive sleeve or other accessories are misaligned with the assembly angle, the valve will leak. 2. Causes of ball valve leaking internal during operation:
Fixing ball valve leakages requires a systematic approach to diagnose and address the issue effectively. For leaks occurring at the handle, turning off the water supply and relieving pressure from the valve is the first step. The packing nut, often responsible for this type of leakage, should then be tightened.
The ball is a sphere that has a hole in its center. The hole in its center is called the bore. The bore serves as the flow opening of the fluid when the cross-section of the fluid flow path and the bore is coplanar. Otherwise, the flow is throttled. A ball valve may have a solid ball or a hollow ball.
Valve automation can help prevent ball valve leakage by eliminating manual operation and reducing the risk of human error. Automated valves can also provide more precise control over the flow rate and pressure, leading to increased efficiency and safety. Consider investing in valve automation if you have a large or complex industrial system.
Leakage can occur due to a variety of reasons, including worn-out or damaged seals, which naturally degrade over time under the stress of controlling high-pressure fluids. Additionally, the failure of stem packing is another common cause, where the seals around the valve stem fail to contain the fluid, leading to leaks.

LEAKAGE ACCEPTANCE RATES FOR METAL & SOFT SEATED VALVES …
FCI 70-2 Class VI (EN 60534-4) is for soft seated control valves but is frequently used as a leakage acceptance test criteria for metal seated isolation valves such as ball and butterfly valves. FCI 70-2 only requires a low pressure test, consequently closure and seat tests should also be done per API 598 (ISO 5208 leakage acceptance rates) or MSS SP-61.
