Application conditions：

Three triple offset butterfly valve for a wide range of applications, including zero leakage isolation, ON-OFF, emergency shutdown and pressure/flow control. All-metal construction available in basic, cryogenic and high temperature configurations.

Product characteristic：

A. The triple offset structure realizes zero leakage of metal seal under high temperature and high pressure.

B. Stellited seat provide excellent durability.

C. Resilient metal seal ring improve the anti-media erosion performance.

D. Double security structure independent anti-thrust ring mounted on top and ends of valve stem,to prevent the valve disc deformation, valve stem dislocation,sealing surface occlusion;setting stem anti fly out structure.Ensure the butterfly valve could safe working in any condition.

E. The one-piece shaft ensures high pressure containment safety/maximum torque seating integrity.

F. Stem combination packing minimize external emission risk.

G. Option—the body and seat adopt a separable structure with convenient installation,adjustment,assembly and disassembly.

H. All-metal construction,essential fire safety.
