Boiler isolation valve

[WilliamTz]

Hello,
Does anyone know the manufacturer of a good quality steam rated butterfly valve both manual and actuated (open/close)
It is for a hot water system with water at 140degC. I have used valves rated to 150degC in the past but they seem to fail after a couple of years hence I would like to go for a steam rated valve. Stop valves and globe valves and gates valves appear very bulky and expensive. The application is a boiler heating system
Regards

Quadax might be ok as well. I think we have one of their butterflies on a steam system and haven't heard maintenance or ops complain.
