Ball Valve Manufacturers in Italy

Valvesonly Europe are trusted Ball Valve Manufacturers in Italy. A ball valve is a type of quarter-turn valve that uses a hollow, perforated, and pivoting ball to control the flow of fluids through it. The ball has a hole or port through its center, and when the valve handle is turned 90 degrees, the hole aligns with the inlet and outlet ports of the valve, allowing fluid to flow through. When the valve handle is turned perpendicular to the ports, the hole is closed off, halting the flow of fluid. This design offers quick and reliable operation for on/off control of fluids and gases in various industries.

Can Ball Valve be used for throttling?

Ball valves are generally not recommended for extensive throttling applications where precise control of flow rate is necessary. This is because ball valves are designed primarily for on/off service and are less effective at regulating flow when partially open. When partially open, the flow passing through a ball valve can cause erosion of the ball and seat due to the fluid's high velocity near the partially exposed port edges. This erosion can lead to premature wear and potential leakage over time. For throttling applications requiring precise flow control, globe valves or control valves with specially designed trim are typically preferred as they can more effectively manage flow rates across a range of openings without significant wear and leakage concerns.

How to repair a Ball Valve?

• Ensure the valve is closed and the water supply to the valve is turned off to prevent any leaks or accidents.


• Open the valve to relieve any pressure in the line downstream of the valve.


• Use a wrench to loosen and remove the valve handle and stem assembly. Set these parts aside.


• Depending on the valve type, you may need to remove a bonnet or retaining nut to access the internals.


• Check the ball and valve seats for wear, corrosion, or debris buildup. Clean these components thoroughly using a cleaning brush or cloth.


• Inspect the O-rings or seals for any signs of damage or wear. Replace them if necessary with new ones that match the valve’s specifications.


• Apply a thin layer of compatible lubricant to the ball, stem, and seals to ensure smooth operation and prevent future sticking or corrosion.


• Place the ball back into the valve body, ensuring it aligns correctly with the inlet and outlet ports.


• Reinstall the stem assembly, handle, and any other removed components in the reverse order of disassembly.


• Slowly open and close the valve several times to ensure it operates smoothly and without any leaks.


• Check for leaks around the valve body and stem connections.


• If the valve still leaks or operates poorly after repair, consider adjusting the stem packing or replacing the valve entirely if it’s severely worn or damaged.


• Once satisfied with the repair, clean up any residual lubricant or debris around the valve, and restore the water supply.
