Proper handling and transportation are essential to ensure the valve arrives in optimal condition:
Packaging: Each valve is wrapped in anti-rust film and protective plastic.
Outer Carton or Crate: Use reinforced corrugated cartons or wooden crates with cushioning to prevent damage.
Thread and Flange Protection: Plastic caps or plugs prevent contamination and physical damage.
Labeling: Include model number, material, pressure rating, and inspection certificate on the outer packaging.
Handling Instructions: Avoid dropping, stacking excessively, or exposing to moisture during transit.
Storage: Store valves in a dry, ventilated area away from corrosive chemicals until installation.
| Component | Description |
|---|---|
| Inner Protection | Anti-rust film or plastic wrap |
| Outer Packaging | Wooden crate or reinforced corrugated carton |
| Cushioning | Foam inserts or cardboard padding |
| End Protection | Plastic caps / plugs |
| Weight Consideration | Based on valve size and material |
Correct installation ensures optimal performance and safety:
Pre-Installation Checks: Confirm the valve is suitable for pipeline size, pressure, and gas type.
Alignment: Ensure pipeline connections are aligned to prevent stress on flanges or threads.
Torque: Apply manufacturer-recommended torque values on flanged or threaded connections.
Orientation: Install the valve in the correct flow direction as indicated by the arrow on the body.
Actuator Connection: For electric or pneumatic operation, follow wiring or air line instructions precisely.
Leak Testing: Conduct pressure tests after installation to confirm leak-free operation.
(For illustration purposes, include a simple schematic showing valve body, ball, seals, flanges, and actuator connection. This can be added to the website or product manual.)
Always depressurize the pipeline before operating or performing maintenance.
Use personal protective equipment (PPE), including gloves and eye protection.
Avoid sudden valve opening or closing to prevent pressure shock.
Ensure proper lubrication of stem and moving components if required.
Do not exceed the rated pressure and temperature limits.
Follow local safety codes and standards for natural gas systems.
