Sealing issues with the sealed air valve?
Thread Content
Due to project requirements, it is necessary to purchase sealed air valves. However, according to the responses from many companies, the leakage rate of these valves is quite high, around 5% on average. Yet our pipeline valves require a high level of sealing performance; slight leakage is acceptable, but not excessive. I would like to ask whether the leakage rate of air valves produced in China is generally high? What are the differences between air valves, gate valves, and butterfly valves? ?
The internal leakage requirement for sealed valves used in air purification systems is 0. Technical issues related to valves can be raised and discussed on the forum.
