Taiwan Jie-Liu VALUE VF-916 Flange-Type High-Performance Double Eccentric Butterfly ValveThis design uses an eccentric disc and offset shaft to integrate a flexible lip-type sealing system into a lightweight and compact valve body. As a result, in many cases, the valve can replace globe and gate valves, but with simpler operation, longer service life, and lower cost. Its outstanding performance makes it widely applicable in many areas such as airport refueling, hydrocarbon processing, HVAC, air handling, chemical processing, purified gas, steam and vacuum services, potable water, and powder and pulp handling.
