High vacuum plug valve, including single seal and double seal vacuum valve types, is suitable for cutting off or connecting air flow in ultra-high vacuum systems. The working medium is clean air and corrosive gases. It adopts touch screen and physical button operation, with control functions such as on/off, stop, emergency stop, etc. There are prominent operation and fault alarm indicators on site, which can achieve remote/local control switching and interlocking. Single and double sealed valves each have a unique working principle to achieve vacuum sealing. Caliber range DN100-DN4000, applicable range 3.5x10-6Pa -1.0x105Pa, valve body and seat leakage rate ≤ 5.3x10-7Pa. L.s-1, valve body applicable temperature ≤ 150 ℃, gas source pressure 0.35-0.8Mpa, is a high-quality choice for high vacuum systems.

High temperature air damper (also known as high-temperature pneumatic damper door, desulfurization flue gas damper door) is the core cutting equipment of the flue gas duct system, designed specifically for high temperature, high dust and corrosive medium working conditions. Through dual dynamic sealing technology and intelligent interlocking control, precise opening and closing of the medium flow channel and zero leakage sealing are achieved, completely solving the energy loss problem caused by high air leakage rate of traditional air doors.

Commonly known as palatal gate, palatal valve, jaw valve, palatal discharge valve, electric palatal gate, arc valve, palatal ash discharge valve, etc., it has a wide range of applications in multiple industries.

The isolation door of the coal mill (also known as the hot air shut-off door of the coal mill) is an important auxiliary equipment of the coal mill, installed in the inlet and outlet air ducts of the coal mill. This product is reliable in operation, flexible in opening and closing, and tightly sealed, fundamentally solving the shortcomings of previous isolation doors that were not tightly closed and had long closing times.

The baffle door is produced and manufactured by Lianyungang Huaneng Electric Power Auxiliary Equipment with imported foreign technology. It adopts a new sealing structure: dual stage soft and hard sealing, and anti adhesion spring plates.

Plug in doors are important auxiliary equipment for boilers, installed on the cold and hot air ducts of boilers in thermal power plants where isolation is required, such as the inlet and outlet ducts of coal mills. This product is reliable in operation, flexible in opening and closing, and tightly sealed, fundamentally solving the shortcomings of previous isolation doors that were not tightly closed and had long closing times. It greatly facilitates equipment switching and shutdown maintenance, and has been widely used in major power plants across the country.

Poppet valve, also known as flat push valve, is a cylinder lift valve. Compressed air enters the air source processing element, undergoes water separation filtration, pressure reduction, and lubricating oil treatment, and then dry, clean, and lubricated air with a certain pressure enters the cylinder through the solenoid valve. The solenoid valve receives signals from the electrical control cabinet, controls the action of the cylinder, and realizes automation processes such as cold air, ash unloading, offline ash cleaning, and return air conversion.
