Main application of control valves is: Transportation of various oil products, steam purging of pipeline, and automatic spraying of fire foam. Butterfly control valve adopts eccentric oblique-cone metal seal technology to achieve zero leakage. Eight kilograms of steam purging pipeline is completed automatically; fire foam spraying is always available, it will quickly open when the control valve is in the loss of signal.

Compared with traditional pneumatic gate valve and ball valve, Triple-eccentric butterfly valve has saved the total engineering cost, and achieved zero leakage.
