Manuel d'utilisation de l'électrovanne Bürkert 134433

1. Introduction et plusview

This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Bürkert 134433 2/2-way servo-controlled solenoid valve. This valve is designed for reliable control of various media, featuring a media-separated pilot valve, suitable for 230V / 50-60Hz electrical systems, and equipped with a G 1/2 connection.

2. Consignes de sécurité

Always adhere to local safety regulations and guidelines when installing, operating, or maintaining the valve. Failure to do so may result in injury or damage to equipment.

• Sécurité électrique : Always disconnect power to the valve and associated circuits before performing any installation, maintenance, or troubleshooting. Ensure proper grounding.
• Sécurité sous pression : Ensure the system is completely depressurized and drained before working on the valve. Sudden release of pressure can cause severe injury.
• Compatibilité des médias : Verify that the valve's materials (brass housing, NBR seals) are compatible with the media being controlled to prevent corrosion or degradation.
• Équipement de protection individuelle (EPI) : Wear appropriate PPE, such as safety glasses, gloves, and protective clothing, when handling the valve or working with the system.
• Personnel qualifié: L'installation et la maintenance doivent être effectuées uniquement par du personnel qualifié et formé.

3. Description et caractéristiques du produit

The Bürkert 134433 is a high-quality 2/2-way servo-controlled solenoid valve designed for robust performance in various industrial applications. Its construction offers enhanced reliability and reduced sensitivity to impurities in the media.

Caractéristiques principales :

• Modèle: Bürkert 5282 134433
• Matériau du boîtier : Durable brass construction.
• Matériau du joint: NBR (Nitrile Butadiene Rubber).
• Impurity Tolerance: Less sensitive to impurities compared to direct-acting solenoid valves, ensuring longer service life.
• Fonctionnement réglable : Features continuously adjustable opening and closing times for precise control.
• Commande manuelle : Some Bürkert solenoid valves, including certain pivoted armature types, may feature a manual override for emergency or testing purposes.

4. Configuration et installation

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

1. Préparation du système : Ensure the system is clean and free of debris before installing the valve. Flush pipes if necessary.
2. Montage: Mount the valve in a position that allows for easy access for maintenance and inspection. The valve can typically be installed in any position, but for optimal performance and longevity, the coil should preferably be in an upright position.
3. Sens de l'écoulement: Observe the flow direction arrow marked on the valve body. Install the valve so that the media flows in the indicated direction (IN-OUT).
4. Connexion de tuyau: Connect the valve to the piping system using the G 1/2 threaded connections. Use appropriate thread sealant (e.g., PTFE tape) to ensure a leak-free connection. Do not overtighten.
5. Connexion électrique : Connect the valve to a 230V / 50-60Hz power supply. Ensure the electrical connections are secure and comply with all local electrical codes. Verify correct voltage and frequency before applying power.
6. Essai: After installation, slowly pressurize the system and check for any leaks. Test the valve's operation by applying and removing power to ensure it opens and closes correctly.

5. Fonctionnement

The Bürkert 134433 is a 2/2-way normally closed (NC) solenoid valve. When power is applied to the coil, the pilot valve opens, allowing system pressure to act on the main diaphragm, which then opens the main valve. When power is removed, the pilot valve closes, and the main valve returns to its closed position.

• Mise sous tension : Applying the specified 230V / 50-60Hz power to the coil will open the valve.
• Éteindre: Removing power from the coil will close the valve.
• Adjustable Times: If equipped with adjustable opening/closing time features, refer to the specific instructions provided with the valve for setting these parameters.

6. Entretien

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

• Inspection de routine : Periodically inspect the valve for any signs of external damage, corrosion, or leaks. Check electrical connections for tightness and integrity.
• Nettoyage: Keep the exterior of the valve clean. Do not use harsh chemicals or abrasive materials that could damage the housing or labels.
• Remplacement du joint : The NBR seals are subject to wear over time, especially with continuous operation or aggressive media. If leaks occur or valve operation becomes erratic, inspect the seals and replace them with genuine Bürkert spare parts.
• Inspection de la bobine : Check the coil for any signs of overheating or damage. A damaged coil should be replaced immediately.
