Best Practices for Ball Valves

Regular Inspection

It’s important to regularly inspect Ball Valves for any signs of wear, damage, or leaks. Did you know thatcatching issues early, potential problems can be addressed before they lead to bigger complications. Regular inspection helps keep the valve functioning smoothly and prevents unexpected failures.

Proper Cleaning

Keeping Ball Valves clean is vital for their long-term performance. Dirt, debris, or buildup can interfere with the valve’s operation and may cause it to stick or leak. Regular cleaning with appropriate methods, such as using a soft cloth, mild detergent, and warm water, helps maintain smooth operation and extends the valve’s life. Avoid using abrasive materials or harsh chemicals that could damage the valve surfaces.

Avoid Over-Tightening

Over-tightening the valve or its connections can cause unnecessary stress on the components, leading to potential damage or leaks. When installing or operating a Ball Valve, apply only the necessary amount of force to keep it securely in place without causing harm.

Proper Storage

When not in use, Ball Valves should be stored in a clean, dry place to prevent corrosion or damage. Storing them properly helps maintain their condition until they are needed for installation or replacement. Keeping them protected from harsh environments extends their usability. At NTVAL, we guarantee that all of our Ball Valves are properly stored to guarantee effective use even in demanding applications.

3. What is a Globe Valve?

A Globe Valve is a type of valve used to regulate the flow of liquids or gases in a pipeline. It has a round body with a movable disk that controls the flow by raising or lowering. They are commonly used when precise control over flow is needed.

Features of Globe Valve

  • Vibration Resistance: These valves are built to operate smoothly in vibrating systems, preventing component loosening and providing reliable performance.
  • Bi-directional Flow: They control flow in both directions, providing flexibility in design and simplifying installation and operation.
  • Low Pressure Drop: Globe Valves are designed to minimize pressure drops, helping maintain system pressure and reduce energy costs.
  • Visual Position Indicator: Many Globe Valves include a visual indicator to easily show whether the valve is open or closed, enhancing safety and efficiency.

Best Practices for Globe Valves

Correct Installation

Proper installation is key to the effective operation of Globe Valves. They should be installed in the correct orientation, with attention to flow direction and alignment. Incorrect installation can lead to poor performance or even damage, so it’s crucial to follow the manufacturer’s guidelines. At NTVAL, we can guide our partners on how to properly install Globe Valves for an effective system project.

Pressure Monitoring

Monitoring the pressure in the system is crucial when using Globe Valves. As a matter of fact, operating them under excessive pressure can lead to valve failure or system damage. Make sure the valve is rated for the maximum pressure in the system and regularly check the pressure levels to avoid issues.

Flushing the System

In systems where debris or environmental contaminants might be present, it’s a good practice to flush the system before operating the Globe Valve. Flushing removes particles that could damage the valve or impair its operation, leading to longer service life and better performance.

Avoid Overheating During Welding

If welding is required near the Globe Valve, take precautions to avoid overheating the valve. Excessive heat can damage the valve’s internal components, such as the seals and seats. Using heat-resistant materials or cooling methods during welding can prevent potential damage.
