Is Your Ball Valve Bad

Time: 8-August 2025 | Source: I-FLOW| Share

Ball valves are built to last, but they don’t live forever. Whether it’s in your home plumbing system or an industrial application, a faulty ball valve can lead to annoying drips, dangerous leaks, or full-on system shutdowns.So how do you know when it's time to replace a ball valve?

5 Warning Signs Your Ball Valve Is Going Bad

1.It’s leaking, even when closed

A ball valve should stop the flow completely. If it’s still leaking when in the “off” position, the ball or seats inside may be worn or damaged.

2.The handle is tough to turn

That handle should rotate smoothly with a firm feel. If you’re straining to open or close it, there might be corrosion, debris, or internal damage.

3.Rust or corrosion is showing

Especially in outdoor or marine environments, rust spots on brass or stainless steel valves mean trouble. Surface rust might just be cosmetic—but internal corrosion is often game over.

4.Flow is weak or uneven

You open the valve, but the flow seems reduced? That could mean the internal ball is damaged, or debris is blocking the opening.

5.Strange noises or pressure fluctuations

If your system is knocking or the pressure keeps changing, a malfunctioning valve could be the source.


What Should You Do

  • If it’s a minor issue, try flushing or cleaning the valve.
  • For corrosion or leaks, replacement is usually the best option.
  • Make sure you’re using the right valve material (brass for domestic water, stainless for aggressive media or industrial use).

Best Practices for Installing Balancing Valves

Walk into any mechanical room, and you’ll quickly understand why balancing valves matter. They quietly determine whether an HVAC system runs smoothly or wastes energy with every cycle. While engineers design the system, it’s the installation that ultimately decides whether a balancing valve performs as intended. To help installers, contractors, and facility managers achieve consistent results, here’s a practical look at the best practices that truly make a difference on-site.

How Long Does Globe Valve Take To Open and Close

When engineers choose a globe valve, they often focus on accuracy, pressure control, and durability. But once the valve is installed, another question always comes up during commissioning: “How long does this valve actually take to open and close?” It sounds simple, yet the answer influences everything—from system safety to actuator selection. In this guide, we break it down clearly and practically, based on engineering experience, manufacturer data, and real usage in industrial plants.
