The company has a group of cooperation teams engaged in the rising stem gate valves, cast iron globe valve, 2pc ball valve, marine butterfly valves, ball valve flange type industry for many years, with dedication, innovation spirit and service awareness, and has established a sound quality control and management system to ensure product quality.
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.
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.
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.
