Copper gate valve is a kind of brass valve. It is composed of a valve body and a valve cover, which is characterized by a tubular structure with a circular channel.

The valve is made of brass and has the characteristics of corrosion resistance and wear resistance. Gate valve is one of the widely used opening and closing devices, the main role is to control the flow rate and pressure of the medium in the pipeline.

Usually installed on horizontal pipes or vertical pipes; It can also be installed on equipment that needs to regulate flow (such as heat exchangers).

Gates can be divided into two categories: open bar gate and plate gate:

The opening forms of open-bar gate have two types: horizontal bar and parallel bar. Plate type and wedge type and wedge with locking nut type in a variety of forms. The flat steel gate made of cast iron material is widely used in the pipe network of water supply, drainage, fire control system and oil supply system as a cut-off and check, generally using hand wheel and handle operation mode. The purpose of opening and closing can also be achieved by the gear rotation mode driven by the transmission device to rotate the screw. The plane sliding support of arch cast iron insert panel can withstand certain reverse pressure thrust and shear force and work normally. This product is widely used in the petroleum industry as a connector for various specifications of oil refining pipes and as a sealing element for cutting media and special requirements of equipment on the pipeline for conveying fluids [1].
