• Tamanho da conexão: 1/2 polegada NPT
• Tipo de válvula: 2/2-way, servo-operated
• Material: Metal (Brass body)
• Aplicativo: Suitable for neutral media

4. Configuração e instalação

Proper installation is crucial for the valve's performance and longevity. Follow these steps carefully:

1. Preparação:
   • Certifique-se de que o sistema esteja despressurizado e drenado.
   • Clean the pipe threads to remove any debris or sealant residue.
   • Verify that the flow direction arrow on the valve body matches the system flow.
2. Montagem:
   • Mount the valve in a position where it is easily accessible for maintenance.
   • The valve can be mounted in any position, but mounting with the coil upwards is recommended for optimal performance and lifespan.
   • Use appropriate thread sealant on the NPT connections.
   • Tighten the valve securely into the piping system, avoiding overtightening which can damage the threads or valve body.
3. Conexão elétrica:
   • Connect the solenoid coil to the appropriate power supply as specified on the coil label.
   • Certifique-se de que todas as conexões elétricas estejam seguras e isoladas para evitar curto-circuitos.
   • Siga os códigos e regulamentos elétricos locais.
4. Verificação do sistema:
   • After installation, slowly pressurize the system and check for leaks.
   • Test the valve's operation by applying and removing power to the coil.

5. Instruções de operação

The Danfoss EV220B 032U7520 is a normally closed (NC) solenoid valve, meaning it is closed when de-energized and opens when energized.

• Energizando a bobina: When electrical power is supplied to the solenoid coil, it creates a magnetic field that pulls the plunger, opening the valve and allowing fluid to flow.
• Desenergizando a bobina: When power is removed from the coil, the magnetic field collapses, and a spring forces the plunger back to its original position, closing the valve and stopping fluid flow.
• Substituição manual (se aplicável): Some models may feature a manual override. Refer to specific product documentation if a manual override is present and how to use it safely. This model typically does not include a manual override.

Certifique-se de que o volume operacionaltage and frequency match the coil's specifications to prevent damage and ensure proper function.

6. Manutenção

Regular maintenance ensures optimal performance and extends the lifespan of your solenoid valve. Always disconnect power before performing any maintenance.

• Limpeza: Periodically inspect the valve for dirt, debris, or corrosion. Clean the exterior with a soft, damp pano. Não use produtos de limpeza abrasivos ou solventes.
• Verificação de vazamentos: Regularly check all connections for signs of leaks. Tighten connections if necessary, but do not overtighten.
• Inspeção da bobina: Inspect the solenoid coil for any signs of damage, overheating, or discoloration. Replace the coil if any damage is observed.
• Internal Inspection (Advanced): For internal component inspection or replacement (e.g., diaphragm, plunger), it is recommended to consult a qualified technician or refer to detailed service manuals provided by Danfoss. Ensure the system is fully depressurized and drained before opening the valve.
