API Triple Eccentric Butterfly Valve

Let's talk about the actual parameters directly to make it easy for you to match your needs: the nominal diameter ranges from DN40 to DN1000, which can handle both small pipes and large-caliber ones; the pressure rating can reach Class150-Class300, maintaining stability even under high-pressure working conditions; the applicable temperature range is -40℃ to 350℃, allowing normal operation whether it's for low-temperature media or high-temperature steam. In terms of materials, the valve body can be WCB, CF8, or CF8M; the sealing surface is made of PTFE or Hastelloy alloy, which is corrosion-resistant and wear-resistant. The connection method is American standard flange, fully complying with the ANSI B16.5 standard, and it can be installed directly on-site, saving the effort of modifying dimensions.

Anyone who has used American standard valves knows that the biggest worries are difficult opening and closing, and poor sealing. This butterfly valve is specifically designed to solve these problems: it adopts a double-eccentric structure for the butterfly plate, which reduces friction during opening and closing, making the torque 25% lower than that of ordinary butterfly valves. Manual operation is effortless, and the electric version also has a fast response speed, making it very flexible to open and close. The sealing surface uses an embedded design, fitting extremely tightly, and the leakage rate is far lower than the API 598 standard, so you can feel at ease even when transporting flammable and explosive media. Additionally, the interior of the valve body is finely polished, reducing the flow resistance of the medium and scaling, and its service life is nearly twice that of ordinary butterfly valves.

As for application scenarios, the range is very wide. It can be used for regulating gas transmission pipelines in the oil and gas industry, controlling the feeding of reaction kettles in chemical parks, and transporting clean fluids in food and pharmaceutical factories. When paired with floating ball valves, the effect is even better. For example, in an LNG receiving station, the American standard butterfly valve regulates the flow of low-temperature media, while the floating ball valve controls emergency shutdown, providing double security guarantees. In overseas oil refining projects, the floating ball valve withstands pressure under high-pressure conditions, and the butterfly valve stably adjusts the flow rate-this combination works extremely reliably.

In the valve business, after-sales service is a must. This American standard butterfly valve comes with a one-year warranty from us. Within the warranty period, as long as the damage is not man-made, all maintenance and replacement of parts are completely free, with no extra cost for you. Moreover, whether you are at home or abroad, if you encounter installation or usage problems, you can contact our technical team at any time-they are online 24 hours a day to answer questions and even provide remote guidance, so you don't have to figure things out by yourself.
