I. Overview of Sliding Gate Panels:
Plate door is a crucial auxiliary equipment for boilers, installed in the cold and hot air ducts of power plant boilers where shutdown and isolation are required, such as: the air ducts of coal mill进出口. This product is reliable in operation, flexible in opening and closing, and tightly sealed, fundamentally solving the shortcomings of previous isolation doors not closing tightly and taking too long to close. It greatly facilitates equipment switching and maintenance shutdowns, and is now widely used in major power plants across the country.

Section II: Key Features of Sliding Door Panels:
The panel door features adjustable and isolating capabilities, offering flexibility and excellent isolation performance.
The 2-blade door operates normally with smooth and effortless operation of the wind door switch, free of any sticking or jamming.
3. After the plug door is closed, there is no internal or external leakage, the shaft seal is in good condition, and there is no gas or air leakage.
High level of automation with remote, close-range, and manual operation functions. 4.
5. The power distribution system can interface with the DCS for automated operation effects.
6. Air leakage rate less than 0.1% after closure.
7. The manufacturing process of electric and manual plug doors complies with relevant industry standards.
8. Electric and manual plug door operation is simple, with a short installation period, which can be completed within a minor maintenance period.
9. Long service life, minimal maintenance required after installation, and can be mounted on any angle of the ductwork.
