Proper maintenance can extend the service life of sanitary diaphragm valves. Regular inspections should be conducted for wear, corrosion, and leakage, and diaphragm valves should be replaced according to wear or regular maintenance cycles to ensure proper installation.
Moderate lubrication should be applied to the moving parts to prevent the diaphragm from getting greasy, and the valve should be kept in a slightly open position to maintain the elasticity of the diaphragm.
1. Inspection and Replacement
- Regular inspection: Regularly check the valve for signs of wear, corrosion, or leakage.
- Diaphragm replacement: Regularly inspect or replace the diaphragm according to physical wear or signs of malfunction at a fixed cycle.
- Diaphragm installation: Ensure proper installation of the diaphragm to prevent cross contamination, performance degradation, or leakage.
2. Handling and Storage
- Proper handling: Follow the correct method provided by the manufacturer to avoid damage to the diaphragm valve.
- Storage: When storing valves, keep the diaphragm slightly open to prevent it from losing elasticity due to prolonged pressure. When not in use, please store in a dry and ventilated room
3. Cleaning and Lubrication
- Cleaning: Before installation, the valve body and interior should be thoroughly cleaned to remove any dirt or dust that may damage the sealing components.
- Lubrication: Lubricate moving parts and seals to reduce friction.
4. Check the working environment
- Before installation, verify that the operating conditions and medium of the valve are suitable for the application.
- During the installation process, ensure that all connecting bolts and components are properly tightened to prevent seal failure
