Will the H71W stainless steel wafer-type check valve leak under pressure?
Thread Content
Hello, everyone! The H71W stainless steel hard-sealed wafer-type check valve does not leak when filled with water under static pressure, but it leaks once pressure is applied using a press. Can such a valve really leak?
Which specific location is leaking? Is it the location of the valve seal, or the valve body itself?
The valve seal doesn’t allow water to leak in under static pressure; it only leaks when pressure is applied
That’s because the pressure it can withstand isn’t high enough! Ask the manufacturer.
Is it leaking drop by drop, or is the water flow leaking? You calculate how many milliliters there will be in the next minute. There are acceptance standards. If it exceeds the limit, it is due to inadequate grinding of the check valve body and the valve disc. It needs to be ground again.
It can be said that no check valve is completely leak-free; as long as the leakage level remains within the specified limits, it is considered acceptable
