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.
