Key Considerations When Removing or Installing an ICF Valve

Key Considerations When Removing or Installing an ICF Valve in Ammonia Refrigeration Systems to Ensure Safety and Optimal Performance

For technical inquiries, please contact the Jabalia Support Team.

1. Initial Safety Procedures 🛑

1. Ammonia Purging:

• Ensure the refrigeration circuit is fully purged of ammonia before starting to avoid exposure to toxic gas.

• Use leak detection equipment to confirm no ammonia residues remain in the area.

2. Personal Protective Equipment (PPE):

• Chemical-resistant gloves, safety goggles, and a suitable respirator mask.

• Protective clothing against chemical leaks.

3. Electrical Isolation:

• Disconnect power supply from actuators and control devices linked to the valve.

2. Removal Guidelines 🔧

1. Recording Valve Settings:

• Document the current pressure and flow settings before removal to simplify re-adjustment after reinstallation.

2. Using the Correct Tools:

• Use specified tools (such as hex keys or torque wrenches) to avoid damaging bolts or valve connections.

• Avoid inappropriate tools that may cause scratches or deformation of the valve body.

3. Handling Internal Components:

• Carefully remove internal parts (e.g., the cartridge) to avoid damaging seals or precision surfaces.

• Place components in a clean, sealed container to prevent contamination by dust or moisture.

3. Installation Guidelines 🛠️

1. Inspection of New Parts:

• Ensure spare parts (cartridge, seals) match system specifications (pressure, temperature, ammonia type).

• Replace all seals (O-rings or gaskets) with new ones to prevent leakage.

2. Cleaning and Lubrication:

• Clean the flow path and connections from any debris or deposits using ammonia-compatible cleaning agents.

• Lubricate seals with suitable materials (e.g., silicone grease) to facilitate proper sealing.

3. Correct Installation:

• Install the valve in the direction of flow (as indicated by the arrow mark on the body) to prevent reverse flow and damage.

• Tighten bolts evenly using the cross-tightening method and according to the specified torque values in the catalog.

4. Leak Testing:

• After installation, perform a pressure test with inert gas (e.g., nitrogen) before refilling with ammonia.

• Use soap solution or chemical detectors to identify any leaks at connections.

4. Additional Technical Tips 📌

• Pipe Alignment:
  Avoid valve stress due to misaligned piping, which may cause cracks or leaks.

• Contamination Prevention:
  Seal valve openings with plastic caps during storage or installation to prevent dust ingress.

• Grounding:
  In electrical systems, ensure proper grounding of the valve and actuators to avoid electrostatic discharge.

❌ Common Mistakes to Avoid:

• Reusing old or incompatible seals with ammonia.

• Skipping leak testing after installation.

• Over-tightening bolts beyond recommended torque, which may cause cracks in the valve body.
