Products Description
1.Small flow resistance.
The medium channel inside the valve body is direct, the medium flows in a straight line, and the flow resistance is small.
2.Less effort when opening and closing.
It is compared with the cut-off valve, because whether it is open or closed, the direction of movement of the gate is perpendicular to the direction of the medium flow.
3.High height, long opening and closing time.
The opening and closing stroke of the gate is large, and the lowering is carried out through the screw.
4.Water hammer phenomenon is not easy to produce.
This is due to the long closing time.
5.The medium can flow in any direction on both sides, easy to install.
Both sides of the gate valve channel are symmetrical.
6.The length of the structure (the distance between the two connecting ends of the shell) is small.
7.The sealing surface is easy to wear, affecting the service life.
When opening and closing, the two sealing surfaces of gate and valve seat rub and slide with each other, which is easy to produce scratch and wear under the action of medium pressure, which affects the sealing performance and shortens the service life.
8.It's more expensive.
The contact sealing surface is more, the processing is more complex, especially the sealing surface on the gate seat is not easy to process, and the parts are more.
9.Simple shape, short structure length, good manufacturing process, wide range of application.
10.The structure is tight.
The valve is good, the channel is smooth, the flow resistance is small, the seal surface is made of steel and hard metal, the service life is long, the use of PTFE, the seal is reliable, the operation is light and flexible.
