Socket Ends Gate Valve Z65X

Socket Ends Gate Valve Z65X Definition and Components

1.1 What is a Z65X Socket Ends Non-Rising Resilient Gate Valve?

Z65X is a specialized gate valve designed for direct connection to plastic piping systems without flanges or mechanical joints:

• Z: Gate Valve
• 6: Socket Ends (for solvent welding or mechanical joint to plastic pipes)
• 5: Non-rising Stem (NRS) design
• X: Resilient (Rubber) Seat

This fire protection water supply features integral socket ends designed to accept the insertion of plastic pipes (PVC, HDPE, PP, etc.) for solvent welding, electrofusion, or mechanical joining methods. It's specifically engineered for plastic piping systems in water distribution, irrigation, and industrial applications.

Pre-Shipment Inspection for Export Socket Ends Gate Valve Z65X and Key Considerations

5.1 Socket-Specific Inspection Protocol

Phase 1: Documentation Review

Z65X REQUIRED DOCUMENTS:

1. Socket Dimension Certificates (per ASTM standards)
2. Pipe Compatibility Certifications
3. Solvent Cement Compatibility Reports
4. Material Certificates for all components
5. NSF/ANSI 61 Certification (for potable water)
6. Pressure Test Certificates
7. Installation Instructions (socket-specific)

Phase 2: Socket Dimensional Inspection

Phase 3: Material Verification

• PMI Testing: Verify body and stem materials
• Rubber Analysis: Verify elastomer type (EPDM, NBR, etc.)
• Coating Inspection: Internal coating integrity
• Socket Material: Verify compatibility with pipe material

Phase 4: Socket Joint Testing

Assembly Test (if possible):

Test Procedure:

1. Prepare test pipe per specifications
2. Assemble valve to pipe using specified method
3. Allow proper cure time (if solvent weld)
4. Perform hydrostatic test at 1.5× rated pressure
5. Check for leakage at socket joint

Valve Pressure Testing:

• Shell Test: 1.5× rated pressure for 2 minutes
• Seat Test: Rated pressure, zero leakage
• Socket Integrity: Visual inspection after testing

Functional Testing:

• Operation Test: Full open/close cycles
• Torque Measurement: Verify within specifications
• Stem Seal Test: Check for leakage

5.2 Special Socket Considerations

Socket Surface Preparation:

• Verify socket interior is clean and free of contaminants
• Check for proper surface texture for bonding
• Ensure no oil or release agents on socket surfaces

Solvent Cement Compatibility:

• Verify valve manufacturer recommends specific cement types
• Check for compatibility with different cement formulations
• Ensure no chemical incompatibility between socket material and cement

Installation Kit Verification:

• If supplied, check installation tools are included
• Verify instructions are clear and complete
• Check cement/primers are within shelf life
