Brass flange gate valve is a kind of opening and closing valve which is widely used in petroleum, chemical, pharmaceutical, electric power and other industries. The valve has the advantages of low flow resistance, labor saving during opening and closing, medium flow in any direction on both sides, small structure length and so on. At the same time, the flange brass gate valve has some disadvantages, such as easy wear of sealing surface, high height, long opening and closing time and so on. Compared with the globe valve, the flow resistance of the flange brass gate valve is smaller, but the height is larger. The working medium of flange brass gate valve is water, gas and oil, and the working temperature is between-20 ℃ and 100 ℃.

Brass flange ball valve is a kind of ball valve made of brass, which is usually used to quickly cut off or turn on the control component of medium flow in pipeline system. The structural design of the flange ball valve absorbs the advanced technology at home and abroad, and the valve seat adopts elastic sealing structure, which is reliable and easy to open and close. The valve stem adopts the downloading structure with inverted seal, and when the valve cavity is pressurized abnormally, the valve stem will not be washed out. At the same time, the product also has a fire-resistant structure, which can be operated reliably in case of fire and has good sealing. According to the needs of users, it can also be equipped with anti-static structure.
