WCB Body Triple Offset Lug Butterfly Valve

Since the advent of the triple eccentric budtterfly valve, in order to meet the requirements of increasingly severe working conditions, it has also experienced a process of self-improvement and continuous development. Even the basic zero leakage can be achieved theoretically with a triple eccentric butterfly valve, but in fact it still depends on careful design and precise manufacturing.

The above valve is Worm Gear Operated Triple Offset Lug Butterfly Valve, suitable for handling the wide range of fluids in oil & gas, petrochemical, chemical, coal, desalination, waterworks, food & beverage industries. Also for solar, geothermal and hydro power, fossil fuels, district heating, mining, shipyards and the aerospace sectors.

The valve body adopts WCB, WCB is covered by ASTM A216 standard, which covers high temperature service for valves.

The characteristics of triple eccentric lug butterfly valve are as follows:

1. Both flow directions can bear pressure, realizing the installation method without flow direction restriction.
2. Strong pressure and high temperature resistance, wide application range;
3. Long service life, can realize repeated switching;
4. The new three-eccentric structure design achieves zero friction, more stable performance and longer service life of the seal. The exquisite design ensures flexible opening and closing of the butterfly valve from low temperature to high temperature, excellent sealing performance, and meets the sealing standard of zero leakage of the valve under severe working conditions.
