Gate valve uses and features

Gate valve is one of the important pipe fittings in conveying fluid medium pipeline. Gate valve is mainly used to cut off medium. It can only be fully open or fully open and cannot be used to adjust flow rate.Its opening and closing parts are the gate, the movement direction of the gate is perpendicular to the direction of the fluid, the gate has two sealing surface, when the gate valve is closed, can only rely on the medium pressure to the sealing surface of the gate to the other side of the seat to achieve sealing, that is, self-sealing.Most gate valves are forced to seal, that is, when the valve is closed, the need to rely on the external force of the medium to force the gate to the seat, to ensure the sealing surface.

Gate valves are widely used in petroleum, petrochemical, chemical, metallurgy, electric power, water conservancy, urban construction, fire fighting, coal and other industries.Gate valves are also valves with distinct advantages and disadvantages.
 
Gate valve features:
 
1.After the gate valve is opened, the internal medium channel of the valve body is straight without any obstruction and the flow resistance is very small. 

2.When the gate valve is opened and closed, the movement direction of the gate is perpendicular to the flow direction of the medium, resulting in less pressure and less effort for opening and closing. 

3.The height of gate valve is large, so the opening and closing time is longer, and water hammer phenomenon is not easy to occur. 

4.gate valve channel is symmetrical on both sides, the medium can flow to both sides in any direction, so the installation of gate valve is very convenient. 

5.Short structure length, good manufacturability and wide application.
