[Public-List] China strikes the A30 - Valve Failure

[Mike Lehman]

I sent the photo of my failed valve to groco and found out it is subject to recall. The shaft was made in China of something that resembles SS, but who knows what it is really made of.

 

Groco was very responsive, and told me they would replace it immediately at no charge. There is a service bulletin about these valves on their web site:

Click on Service Manual, then on the picture of the valves. There is a good desription of the problem and how to identify if you have any of these valves and the years of production.

I have seen these failures on gate valves, but never before on bronze Groco ball valves (neither had Fawcett's or Jack Hornor, marine surveyor), since the shaft is sealed from the ball by a teflon seal. So it makes me wonder how crevice corrosion could cause this failure, and makes me a bit nervous about the other Groco valves on board. They all look fine from the outside, but so did this one, and it is only about 5-years old.
