Features of Lever Lug Butterfly Valve
- DN100 / 4 inches indicates that the valve’s Nominal Diameter (DN) is 100 millimeters, which is approximately equal to 4 inches.
- PN16 signifies a Nominal Pressure rating of 16 bar.
- Features a replaceable seat design, meaning that the seat material can be replaced or repaired without the need to replace the entire valve assembly. This feature helps extend the valve’s service life and reduces maintenance costs—a significant advantage, given that the valve body typically accounts for a substantial portion of the total cost.
- Operated via a handle. Its simple, cost-effective structure makes it an ideal choice for smaller valves (DN ≤ 300), as the handle allows for easy and convenient control of the valve’s opening and closing functions.
- Features a lug-type connection; this means the valve body is equipped with threaded holes. However, please note that this specific model—with its replaceable soft seat—is not suitable for use as an end-of-line valve.
- Suitable for use across a wide range of industries, including water treatment, HVAC systems, chemical processing, and irrigation systems.\
- The replaceable seat design offers superior sealing performance and facilitates easier maintenance thanks to the elastic properties of its soft seal, ensuring minimal leakage when the valve is closed.
- Capable of handling various media—such as water, oil, and gas—depending on the specific materials utilized in the valve’s construction.
