የአሠራር መመሪያዎች
The Danfoss EV225B is a normally closed (NC) solenoid valve. This means the valve is closed when the coil is de-energized and opens when the coil is energized.
- የመጀመሪያ ጅምር፡ After installation, slowly introduce steam into the system to check for leaks.
- ኮይልን ማነቃቃት; የተገለጸውን ጥራዝ ተግብርtage to the solenoid coil. The valve will open, allowing steam to flow.
- የኃይል ማመንጫውን ማጥፋት; ጥራዝ ያስወግዱtage from the solenoid coil. The valve will close, stopping the steam flow.
- ቀጣይነት ያለው አሰራር; The valve is designed for continuous duty within its specified operating parameters. Monitor system pressure and temperature to ensure they remain within the valve's limits.
ጥገና
Regular maintenance ensures the longevity and reliable operation of the Danfoss EV225B solenoid valve.
Scheduled Inspections
- Periodically check for external leaks around the valve body and connections.
- Inspect the solenoid coil for any signs of overheating or damage.

Cleaning and Component Replacement
- If flow is restricted or the valve is not operating correctly, it may require internal cleaning.
- Before disassembling, ensure the system is completely depressurized and cooled.
- Carefully disassemble the valve, paying attention to the arrangement of internal components.
- Clean all parts, especially the Teflon seals and orifice, using appropriate cleaning agents for steam systems.
- Replace any worn or damaged seals and O-rings with genuine Danfoss spare parts.
- Reassemble the valve, ensuring all components are correctly seated and tightened.
