Seeking advice from experts: For heat transfer oil pipelines operating at around 300°C, what type of valve is suitable to be used for connecting them to the main pipeline?

I need help from experts. For heat transfer oil pipelines operating at around 300°C, what type of valve is suitable to be used as the isolation valve between this pipeline and the main pipeline? According to the standards, globe valves and gate valves are both acceptable; however, the manufacturer insists on using a gate valve. Is this acceptable? What are the standard guidelines for this?
There is no solid basis for this; if the goal is simply to cut off flow, a gate valve will suffice, while if flow regulation is required, a globe valve is a more appropriate choice.
Most domestic applications for heat transfer oil use bellows stop valves.
It’s the stop valve; if you fully open the 300-series gate valve, it will get jammed
You can ask the manufacturer to provide the reasons for the chosen options
For our 300-degree thermal oil, gate valves are suitable; ball valves can also be used
Using gate valves provides good shut-off performance and reduces the risk of internal leakage
