Descripció del producte
The Danfoss Solenoid Valve 032F1157 is a 3/8" EVR 3 ODF valve designed for use in various refrigeration systems. It is a normally closed, straightway valve without a manual stem, primarily functioning as a body-only unit. Constructed from stainless steel, it ensures durability and reliability in demanding environments.
Typical applications include refrigeration systems in air conditioning and food service industries, such as walk-in cold rooms, display freezers, and refrigerators. These valves are also suitable for icemakers and ice cream machines, where they are designed to withstand additional stress from rapid defrosting cycles or short hot gas injection cycles, depending on the specific application.

Figura 1: Danfoss Solenoid Valve 032F1157. This image shows the main body of the solenoid valve, made of brass, with a cylindrical metal component (the solenoid coil housing) extending upwards. Two copper pipe connections extend horizontally from the main body, indicating its use in fluid systems. The valve appears to be designed for inline installation.

Configuració i instal·lació
Installation of the Danfoss Solenoid Valve should only be performed by a qualified technician familiar with refrigeration systems and relevant safety procedures. Ensure the system is completely depressurized and isolated before beginning installation.
- Preparació: Ensure the system is shut down, depressurized, and all refrigerants are safely recovered or isolated.
- Ubicació: Install the valve in a location that allows for easy access for future maintenance and inspection. Ensure the flow direction arrow on the valve body matches the system's flow.
- Connexió: Connect the 3/8" ODF (Outside Diameter Flared) connections to the corresponding system piping. Use appropriate tools and techniques to ensure leak-free connections.
- Coil Installation (if separate): If the solenoid coil is supplied separately, ensure it is correctly mounted onto the valve body according to Danfoss instructions.
- Prova de fuites: After installation, perform a thorough leak test using an appropriate method (e.g., nitrogen pressure test) to ensure all connections are sealed.
- System Recommissioning: Slowly reintroduce refrigerant and pressure to the system, carefully monitoring for any anomalies.
Refer to specific system diagrams and local codes for detailed installation requirements.
Instruccions de funcionament
The Danfoss Solenoid Valve 032F1157 operates automatically as part of the refrigeration system's control circuit. As a normally closed valve, it remains closed when de-energized and opens when the solenoid coil is energized, allowing refrigerant flow.
- Funcionament automàtic: The valve's opening and closing are controlled by the system's electrical signals to the solenoid coil.
- Direcció del flux: Always ensure the valve is installed with the correct flow direction as indicated by the arrow on the valve body.
- Seguiment: Regularly monitor system pressures and temperatures to ensure the valve is functioning correctly within the system's design parameters.
Manteniment
Regular maintenance ensures the longevity and reliable operation of the solenoid valve. All maintenance procedures should be performed by qualified personnel.
- Inspecció periòdica: Visually inspect the valve and connections for any signs of leaks, corrosion, or physical damage.
- Coil Check: Ensure the solenoid coil is securely seated and free from excessive vibration or overheating.
- Neteja: Mantingueu l'exterior de la vàlvula net i lliure de residus.
- Comprovacions del sistema: Include the valve in routine system performance checks, verifying proper opening and closing cycles.
- Substitució: If the valve shows signs of wear, leakage, or malfunction, it should be replaced with an original Danfoss part to maintain system integrity.
Nota: This valve is designed as a body-only unit without a manual stem, limiting field serviceability to external checks and coil replacement if applicable.
Resolució de problemes
If the solenoid valve is not functioning as expected, consider the following common issues. Always ensure safety precautions are followed before attempting any troubleshooting.
| Problema | Causa possible | Solució |
|---|---|---|
| Valve does not open when energized. | No power to coil; faulty coil; clogged orifice; excessive pressure differential. | Check electrical connections and power supply. Test coil resistance. Inspect for internal blockages (requires system depressurization). Verify system pressures are within valve limits. |
| Valve does not close when de-energized. | Debris in valve seat; faulty coil (stuck open); incorrect pressure differential. | Depressurize system and inspect valve for debris. Replace coil if faulty. Ensure system pressures allow for proper closing. |
| External leakage. | Loose connections; damaged valve body or seals. | Tighten connections. If valve body or seals are damaged, the valve must be replaced. |
For issues not listed or if solutions do not resolve the problem, contact Danfoss technical support or a qualified refrigeration technician.
