Taiwan's Jie-Liu VALUE VF-913A multi-lug double eccentric butterfly valve features a design that incorporates an eccentric disc and offset shaft, integrating a flexible lip seal system into a lightweight and compact valve body. As a result, in many applications, the valve can replace globe and gate valves, offering simpler operation, longer service life, and lower cost. Its outstanding performance makes it widely used in airport refueling, hydrocarbon processing, HVAC, air handling, chemical processing, purified gases, steam and vacuum services, potable water, powder and pulp handling, and many other applications.

The lug-style design facilitates connection between flanges and saves pipeline length.
