What is the specific function of the plug valve in the catalytic regenerator?

1. The plug valve of the catalytic regenerator is installed at the bottom of the catalyst feed riser, which is arranged coaxially with the regenerator.
2. It controls the amount of catalyst that flows from the settler, through the catalyst feed riser, to the regenerator.
3. At the bottom of the plug valve, there is a pressurized air lift ring that transports the catalyst exiting the valve in a dilute phase to the distributor, from where it then enters the regenerator

What the guy is talking about seems to be a regenerative slide valve. The plug valve is a special valve installed at the bottom of the regenerator, used to control the amount of catalyst that moves between the two catalyst tanks. What I want to know is its working principle – how is it controlled?

1. Whether it is a plug valve for use in raw material handling or any other type of plug valve, its function remains the same. 2. As the name implies, a plug valve uses a plug that moves up and down to control the cross-sectional area of the flow channel. 3. The control signal for such a valve can come from the pressure difference before and after the valve, or it can be controlled using parameters such as the volume in the stripping section of a catalytic settler. 4. There are two methods for driving plug valves: pneumatic control and electro-hydraulic control. 5. For electro-hydraulic control, options include local mechanical manual operation, local hydraulic control, and remote automatic control. 7. A distinct feature of plug valves compared to other valves is the presence of an automatic expansion compensation system. 8. Plug valves come equipped with 6 alarm functions and 3 locking functions, such as locking in case of loss of tracking. For more detailed information, refer to the manual of the plug valve
