Ball valves are essential components in a wide range of applications and industries due to their reliable flow control capabilities, mainly in industrial processes, water supply, and wastewater treatment applications.

These valves utilise a spherical ball with a hole in the centre to regulate the flow rates of liquids or gases and have on/off capabilities. Their versatility stems from their ability to handle high operating pressures and are corrosion resistant.

Ball valves offer a tight seal when in a closed position, ensuring no leakage or loss of pressure. They also boast a compact design, making them suitable for installations where space is limited or when a streamlined appearance is desired.

Its valve handle allows for ease of operation, enabling users to open or close the valve quickly. This simplicity and convenience make ball valves highly user-friendly, even for those with limited technical knowledge.

At Laminar, we offer various construction, designs, sizes, pressure ratings and body materials.

Ball valves utilise a spherical ball with a hole in the middle to control the flow direction of water, oil, or gas. They effectively prevent backflow when closed.

One of the primary uses of ball valves is to regulate the flow of liquids or gases. When the valve handle is turned to the closed position, the ball inside blocks off the flow completely. This feature makes ball valves ideal for applications requiring precise control over fluid flow.

The ball valve design ensures that you can expect easy operation and durability, making it an excellent choice for shutoff. Most commonly made from stainless steel or carbon steel, these valves can withstand high pressures and temperatures without compromising performance. The valve handle provides a simple mechanism for users to quickly open or close the valve.

A ball valve should be installed in any application where precise fluid flow control is required. Its easy operation and tight seal make it ideal for residential, commercial, and industrial applications. This includes water supply systems, pipelines, chemical processing systems, fuel lines, etc.

Choosing the connection type, appropriate size, and pressure rating based on the application is highly important. Laminar offers a wide range of connection types, including flanged, socket weld, butt weld, and threaded end connections.
