Ball Valve Installation Guide: Avoid These 5 Mistakes

A ball valve is only as good as its installation. Even the best product can fail—or leak—if installed improperly. In this guide, we’ll walk you through the five most common mistakes users make when installing ball valves, and how to avoid them.

1. Mistake #1: Using the Wrong Sealant

• Avoid using PTFE tape on certain thread types if the valve requires a metal-to-metal seal.

• Overusing thread sealant can damage internal seals.

2. Mistake #2: Over-Tightening

• Excess torque can crack the housing or deform threads.

• Always follow recommended torque specs.

3. Mistake #3: Poor Alignment with Piping

• Misaligned valves lead to leaks or mechanical stress.

• Use pipe supports and alignment tools.

4. Mistake #4: No Testing After Installation

• Always perform leak and function tests.

• Use water or air under controlled pressure to validate integrity.

5. Mistake #5: Ignoring Valve Orientation

• Some ball valves are directional, especially those with flow arrows.

• Improper orientation can reduce lifespan or affect function.
