Product Description

China Lug high performance butterfly valve manufacturer, factory, company and supplier, Lug high performance butterfly valve provides a cost-effective solution for a wide range of applications where bubble-tight shut-off is required. Lug high performance butterfly valve adopts an eccentric disc and offset shaft, the design incorporates the flexible-lip sealing system into a lightweight, compact body. The result is that in many cases lug high performance butterfly valve can replace globe valve and gate valve yet easier operating, longer lasting and lower cost.

Lug high performance butterfly valve widely used in many applications such as Airport refueling, Hydrocarbon processing, HVAC, Air treatment, Chemical processing, Purified gas, Steam and vacuum services, Potable water, Powder and pulp processing, etc.Wafer design makes the valve convenient for connection between flanges and save length in pipe line.
