Thanks JLSeagull,
Valve built-in to the line with screw structure.
Fujikins decleration is ;
"The valve is rated at ANSI Class 4500 for pressures.
At temperature at 38°C maximum pressure is 74,4 Mpa
At temperature at 600°C maximum pressure is 30,2 Mpa"
Hi friends;
I inquire needle valve manufacturers for Class 4500 pressure ratings.(For example Fujikin needle valve)
If you have info about it, please inform me.
Have a nice days and thank you for your supports.
