    In my opinion, rotary valves are not suitable in this service. You should consider other feeding devices such as screw feeders followed by mass flow meters. The reason is that at these high temperatures the rotor may bind inside the valve body due to very high differential expansions and contractions.

    If you need our help in selecting a suitable feeding device, please contact us.
