Ball valves for demanding shut-off and control applications
Versatile and reliable
Neles ball valves are designed to deliver reliable control, on-off and emergency shutdown performance in a wide range of end use applications and customer industries, ranging from an array of pulp and paper industry applications to service in the chemical, petrochemical and refining industries. We provide both industry-leading automated ball valves and manual ball valves.
Full range of ball valves
Our ball valve offering includes trunnion mounted ball valves, top entry ball valves, seat supported ball valves, high-pressure ball valves, pocket feeder valves and full bore ball valves. We offer a range of materials and coating ranging from valves utilizing metal-to-metal seat technology to ceramic balls and PFA coated ball valves.
Safety and sustainability
All Neles ball valves are engineered, built and tested to be both safe and sustainable. They ensure the lowest possible emissions in accordance with ISO 15848 and certified fire safety according to API 607. Our ball valves are also SIL 3 certified. Features such as the anti-blowout stem featured in many valves further improve safety.
World-class noise and cavitation reduction
Neles is well known for its industry-leading noise attenuation and cavitation eliminating technologies. Our Q-trim™ and Q2-trim™ anti-cavitation and noise attenuation technologies continue to set the standard in industrial applications. They are a feature that can help your ball valve outperform others in control applications and extend suitability into increasingly demanding heavy duty applications.
What is a ball valve?
Ball valves are durable, performing well after extended operating cycles, even in fouling and dirty applications, under high differential pressures. Reliable, tight closing after long periods of staying unoperated is one of ball valves advantages in shutoff applications. As the name suggests, a ball-shaped trim is used to control the flow of media. An open ball valve acts like a piece of pipe, creating little to no interference to passing through flow. When the ball is rotated clockwise at 90°, the valve is completely shut. The bore of the ball and its high inherent capacity (Cv) can be utilized also to control high fluid volumes with small energy losses. Ball bore can also be equipped with noise and cavitation dampening trims without sacrificing flow capacity in control service.
Depending on the industrial process, application and flow media, different types of ball valves are available, ranging from metal-seated ball valves to soft-seated ball valves in both automated and manual variants. Different constructions, coatings and noise and cavitation elimination solutions are available to ensure process suitability and lasting reliable performance.
