Hot blast valve have types of common type, micro water energy saving type, special water chamber lining type, drive electrically or hydraulically.
The new type of lining hot air valve produced by our company breaks through the common problems existing in the valve at home and abroad, and integrates many revolutionary products with many patents. Its main technical characteristics are
（1）Full floating sealing technology for stainless steel or alloy catalytic valve stem. The utility model has the advantages of strict sealing, simple lubrication and low friction resistance, which can ensure that there is no leakage and maintenance during the life of the generation valve.
（2）. The fire resistant lining is fully covered in the part of the hot air flow through the inner cavity of the valve body. The antioxidant capacity of each part is synchronized.
（3）. For the cooling of the sealing surface of the valve body, the elliptical asymmetric water cavity structure is proposed creatively, which not only has high strength and good stiffness, especially without weld exposure, but also adds advanced floating grinding technology, even if the valve water pressure and water quantity can not meet the normal requirements in a short time, it can ensure the normal use of the valve door, and will not be damaged in a short period of time.
（4）. The explosive composite technology is used to improve the oxidation resistance of the valve plate.
