A105/LF2 Cl.1 dual certified for High temperature

[Luigi De Micheli]

Is possible use A105/LF2 dual certified cl.1 for service temperature 400°C ?

In The B16.34, A105 and LF2 means 425°C ( but not raccomanded)

Ask the valve manufacturer. Even if the steel parts are ok, the sealing parts likely will not be suitable for that high temperature unless specifically designed for it.
