It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

How many cubic millimeters leak in 1 second.

Valve leakage refers to the working pressure of the valve under the standard balance (design).

1. The ratio of the allowable flow rate to the leakage volume of this valve. Such as 1, 3/10,000;

2. Allowable (occurring) actual (liquid) leakage. e.g. 5 ml min;

3. Allowed (occurring) actual (gas spring silver body) leakage. e.g. 3 minutes (the number of bubbles coming out of the downstream);

ANSI (American National Standard) standard, which is used for general straight-through single-seat valves;

API 598 (American Petroleum Institute Standard), which is used for ball valves, butterfly valves, gate valves, etc.

The unit of general use is mm3 s, ml min, or the number of drops, the number of bubbles;

Please refer to the Valve Design Manual - Valve Leak Testing;
