Low-pressure leakage prevention performance of floating ball valves under high pressure
Thread Content
After testing the 3000 WOG floating ball valve at 2000–2500 psig, the customer conducted a low-pressure test at 60–100 psig and discovered leakage at the ball seat. Is **such a test reasonable?** Thank you!
Low pressure should be measured; floating high pressure is easy to seal, while low pressure is difficult to seal
Thank you. Won’t the valve seat downstream, after being subjected to high pressure, deform under stress and thus affect the low-pressure seal?
It’s possible; the quality of the valve seat must be good to avoid this problem
Low-pressure testing probably doesn’t hold much significance.
It seems reasonable; low pressure is acceptable
