Product Description
Gate valve advantages
1. Small flow resistance. The internal medium channel of the valve body is straight, the medium flows in a straight line, and the flow resistance is small.
2. It saves effort when opening and closing. It is compared with the stop valve, because whether it is open or closed, the movement direction of the gate is perpendicular to the direction of medium flow.
3. Large height, long opening and closing time. The opening and closing stroke of the gate is relatively large, and the lifting and lowering is performed by a screw.
4. Water hammer is not easy to occur. The reason is the long shutdown time.
5. The medium can flow in any direction on both sides, making it easy to install. The gate valve passage is symmetrical on both sides.
6. The structural length (the distance between the two connecting end faces of the shell) is small.
7. The universal valve has a simple shape, short structural length, good manufacturing process, and wide application range.
8. The structure is compact, the special valve has good rigidity, smooth channel, and small flow resistance. The sealing surface is made of stainless steel and carbide, which has a long service life. It uses PTFE packing to ensure reliable sealing and light and flexible operation.
2. There is relative friction between the sealing surfaces, resulting in greater wear and tear. It is inconvenient to repair after the sealing surfaces are worn.
3. The structure size of the middle cavity of the valve is large, resulting in a long structure length, large appearance size, and large installation space. Large-diameter gate valves are especially bulky.
4. The valve opening and closing time is long
5. It can form a closed valve cavity, so a pressure relief structure should be installed to prevent abnormal pressure increase in the middle cavity when necessary.

Gate valve disadvantages
1. Generally, gate valves have two sealing surfaces, and the processing and manufacturing are more complicated than globe valves.2. There is relative friction between the sealing surfaces, resulting in greater wear and tear. It is inconvenient to repair after the sealing surfaces are worn.
3. The structure size of the middle cavity of the valve is large, resulting in a long structure length, large appearance size, and large installation space. Large-diameter gate valves are especially bulky.
4. The valve opening and closing time is long
