Installation and Maintenance

Installation key points
- Flow direction identificationInstall in the direction of the valve body arrow to avoid sealing damage caused by reverse flow.
- vertical installationPriority should be given to vertical installation (with the valve core perpendicular to the ground) to reduce valve core wear (horizontal installation requires additional support brackets).
- electrical connectionEnsure the correct polarity of the power supply (24 V DC+connected to the "+" terminal) to avoid short circuits or reverse connections that may damage the coil.
- grounding protectionThe casing of the solenoid valve needs to be reliably grounded (grounding resistance<10 Ω) to prevent static electricity or lightning strikes.
routine maintenance
- regular inspectionCheck the sealing components for aging every 3 months (if cracks or deformations appear, they need to be replaced).
- Cleaning and maintenanceBlow the dust inside the valve body with compressed air (avoid using corrosive cleaning agents).
- Lubrication requirementsStainless steel valve bodies do not require lubrication, while brass valve bodies can be coated with a small amount of silicon-based grease (such as Molykote 111).
troubleshooting
- Valve does not operate：
  - Check if the power supply is normal (use a multimeter to measure if the voltage is within the rated range).
  - Confirm if the coil is damaged (measure resistance value, open circuit indicates coil burnout).
- Valve leakage：
  - Check if the sealing components are installed properly or aged (replace with sealing rings of the same model).
  - Confirm whether the medium contains particulate impurities (a filter with a filtration accuracy of ≥ 50 μ m needs to be installed).
- Slow response：
  - Check if the voltage is too low (such as 24 V DC dropping below 20 V will cause insufficient suction).
  - Clean the impurities between the valve core and valve seat (wipe with a soft cloth to avoid scratching the sealing surface).
