Overview

Electric gate valve DN200 is used as a shut-off medium in pipelines, and should not be used for regulation or throttling When the gate valve is fully opened, the entire flow is straight through, and the pressure loss of the medium during operation is small. However, when the gate of the gate valve is partially opened, the high-speed flowing medium will cause vibration of the valve, which may damage the sealing surface of the gate and valve seat. Throttling will cause erosion of the gate by the medium Therefore, gate valves are usually suitable for operating conditions that do not require frequent opening and closing, and maintain the gate fully open or fully closed

Electric gate valve DN200Product Introduction:

Gate valves are used as shut-off media in pipelines and should not be used for regulation or throttling When the gate valve is fully opened, the entire flow is straight through, and the pressure loss of the medium during operation is small. However, when the gate of the gate valve is partially opened, the high-speed flowing medium will cause vibration of the valve, which may damage the sealing surface of the gate and valve seat. Throttling will cause erosion of the gate by the medium Therefore, gate valves are usually suitable for operating conditions that do not require frequent opening and closing, and maintain the gate fully open or fully closed

Electric gate valve DN200Structure and characteristics:

1. Carefully selected materials that meet relevant domestic and international standards, with high overall quality.

2. Meet the requirements of domestic and international standards, with reliable sealing, excellent performance, and beautiful appearance.

3. The sealing pair pairing is reasonable. The sealing surfaces of the gate and valve seat are made of Stellite cobalt based hard alloy with different hardness, which is welded together for reliable sealing, high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance, and long service life.

4. The valve stem has undergone quenching and surface nitriding treatment, providing excellent corrosion resistance, abrasion resistance, and wear resistance
5. Adopting a wedge-shaped elastic gate structure, thrust bearings are installed on the medium and large diameters with low friction, and equipped with an impact handwheel for easy and smooth opening and closing. Widely applicable as an opening and closing device for connecting or cutting off the medium in oil and steam pipelines such as petrochemicals and thermal power plants.

6. Various piping flange standards and flange sealing surface forms can be adopted to meet various engineering needs and user requirements.
