Hi,

Suggest to ask someone who was there when building/designing the Plant
If this manufacturer limit to 30 years or older and your Plant is in Europe, I would say one of these:
Gulde (bought by Emerson) if this is the case than it might be a Gate valve. They don't produce this anymore
Neles (bought by Metso) can be Plug valve or Gate valve
HP valve --> the yoke similar to their current design, might be their trademark
Or might be one of Fisher or Flowserve portofolio.
And also some possibilities of your local manufacturer (Nederlands/German/Italy) and probably exported from USA

One thing almost for sure, the "manufacturer" will not offer like to like replacement or similar spare part due to obsolete. And will offer you up to date alternative

one of my Plant's 40 year old Gulde

Maybe someone more senior than me can provide better insight.
PS: Some Gate valve during this era were and still designed as throttling valve. IMHO, your valve is already reach end of lifetime

Regards,
MR



All valves will last for years, except the ones that were poorly manufactured; are still wrongly operated and or were wrongly selected

Danlap (MR) Thank you for your answer.
Many options...
My factory is located in Poland (EUROPE)
BW valve is EDWARD, so I suspec that the other one (with flanges)is EDWARD too - but cannot be sure. Probably gate valve.
Anyway, thank you so much.
regards
Tomasz

Edward Valves are of US origin; they're still trading as a Flowserve brand.
