Installation & Handling Tips

For best results, follow these installation and maintenance practices:

• Apply thread sealant or PTFE tape to male threaded ends before installation to prevent leaks.
• Ensure pipes are properly aligned to avoid undue stress on valve threads.
• Avoid overtightening, which can damage threads or crack fittings.
• Confirm flow direction and orient for easy handle access (valve is bi-directional).
• Perform regular inspections to ensure the valve maintains optimal seal and ball movement in high-use environments.
