Features of Lever Lug Butterfly Valve
-
The DN100 butterfly valve has a nominal diameter of 100 mm (4 inches) and a rated pressure of PN16.
-
The replaceable seat design allows for seat replacement without replacing the entire valve, reducing maintenance costs and extending service life. This design is particularly useful for long-term use, as the valve body is typically the most valuable component.
-
Handle operation allows for quick and easy opening and closing. This lever lug butterfly valve compact design and ease of operation make it the most cost-effective choice for small-sized pipelines, especially DN300 and below.
-
The lug-type valve body design with threaded mounting holes ensures secure installation on pipelines. It should be noted that due to its replaceable soft-seal design, it is generally not recommended for use at pipeline ends.
-
This lever lug butterfly valve Widely used in water treatment, HVAC systems, irrigation networks, and general industrial piping. Depending on the selected valve body, disc, and seat materials, it can handle media such as water, oil, and gas.
