Unusual Valve Identification 2

[Wes-in-WV]

I have a 16" gate (I think) valve (pic attached). The bolt circle seems to match standard 16-150, but the face to face is only 12". Everything else I can find is 16" face to face. I need to replace and I'm getting ready to use a wafer and spacer (to avoid messing with the old piping). Can anyone ID the valve company (VC logo) or where I can find a similar model? I've been asking around to vendors without success. Thanks.

That looks like a knife gate, often used in pulp and paper.

I don’t recognise the manufacturer myself but might be worth reaching out to someone like Shipham Valves (in the UK). I’m being subjective here but I know that they’ve done ‘strange’ sizes in the past.

It looks like a Non rising Stem gate valve of some type.

I suspect it's not a B 16.35 valve but more likely and old BS valve or possibly a PN 10 rated valve.

Those flanges look a bit thin for ASME B 16.5 flanges.

Is there any other info on the valve or in records anywhere?
Location and how old? - West Virginia but age?

Thanks for the link Fuzzbox, I'll check them out.

LittleInch, I checked the bolt circle diameter, but didn't think about the flange thickness. That's a good idea. I haven't been able to find any records or age of the valve.

Best I can find is an EN 558-2 (not -1)

F2F is 310 for a 400mm

and go to appendix 4

Also this lot - Page 3

Seems to be also DIN 3202 -F4

There is a big "16" on the side, so I'm thinking PN16.

I found this [URL unfurl="true"]https://www.hawle.com/en/products/gate-valves/e3-gate-valve-pn10-pn-16-4000e3/[/url] as well. Face to face looks correct.

Thanks for pointing me in the right direction!

hope you find one that fits - many suppliers only seem to go to 12", but that spec is the only one I've found which gets close to your dimensions

Your post indicates that you are from West Virginia. If so, it is very unlikely that the valve is a British standard. It is probably made in the United States.

From the picture, this appears to be a water works application. How old is the piping? You should have a drawing, no? Is the piping cast iron? Do you have a better picture of the valve symbol?

Henry Pratt AWWA standard

So many corporations have come and gone over the years that it is unlikely that the original valve manufacturer is still around.

You haven't provided enough information about the application to determine if it is acceptable to switch from a gate valve to a butterfly valve. What is the fluid and pressure?

Any idea how old the piping and valve could be? Possibly, your VC should be CV, meaning Chapman valve. They were a big player from the late 1800's to around 1960. They were eventually taken over by Crane. Not much information available on-line because of the time frame, but I did manage to find one of their old catalogs and something similar appears on pages 36 and 37. Dimensions do not exactly match what you are saying the face-to-face dimension is, but otherwise, the valve looks pretty close.

Believe you are correct, it is a Chapman valve as identified by the symbol.

Chapman Valve Manufacturing Co. was located in the town of Indian Orchard, near Springfield, MA. Chapman had its own complex history. During World War II it supplied valves to the Manhattan Project and the Atomic Energy Commission. After the war, Chapman machined enriched uranium rods into reactor fuel slugs for the Brookhaven National Laboratory. The company may also have conducted rolling operations on uranium metal as late as 1949. The hydrant and valve factory was still active under various company names until 1971.
