1. Sewage Treatment Plants
DN500 flanged knife gate valves are widely used in sewage treatment plants for inlet, outlet, and sludge treatment processes. Their strong cutting ability effectively handles media containing solid particles, ensuring stable system operation.
2. Mining and Metallurgical Industries
In the mining and metallurgical sectors, DN500 flanged knife gate valves are used in pipelines transporting ore slurry, tailings, and high-concentration media. Their wear resistance and corrosion resistance make them an ideal choice.
3. Power Industry
In power plants, DN500 flanged knife gate valves are used in ash handling systems, effectively cutting off high-concentration ash and ensuring equipment safety.
4. Chemical Industry
In chemical production, DN500 flanged knife gate valves are used in pipelines transporting corrosive media. Their corrosion-resistant materials can effectively handle various chemical substances.
5. Water Conservancy Projects
In large-scale water conservancy projects, DN500 flanged knife gate valves are used for sluice control, regulating water flow, and ensuring the normal operation of hydraulic facilities.
1. Media Requirements
DN500 flanged knife gate valves are suitable for applications involving solid particles, high-concentration, and corrosive media, such as sewage, ore slurry, and ash.
2. Temperature and Pressure
These valves are suitable for medium to low-temperature environments, typically operating between -29°C and 200°C, with pressure ratings of PN10 to PN16.
3. Installation Environment
Valves should be installed in dry, well-ventilated areas, avoiding direct sunlight and rain erosion to ensure long-term stable operation.
4. Operation Methods
DN500 flanged knife gate valves can be operated manually, electrically, or pneumatically, allowing users to choose based on actual needs.
1. Installation Steps
●Inspect the valve and pipeline interfaces to ensure no damage or impurities.
●Align the valve flange with the pipeline flange, insert bolts, and tighten evenly.
●After installation, check if the valve opens and closes smoothly to ensure no jamming.
2. Operation Steps
●For manual operation, turn the handwheel clockwise to close the valve and counterclockwise to open it.
●For electric or pneumatic operation, use the control box or pneumatic actuator to open and close the valve.
●During operation, monitor the valve status to ensure it opens and closes fully.
3. Maintenance
●Regularly inspect the valve's sealing performance and replace worn seals promptly.
●Keep the valve clean and regularly remove impurities inside and outside the valve body.
●Perform regular maintenance on electric or pneumatic actuators to ensure proper operation.
