Triple Eccentic Butterfly Valves
BFV03
Unparalleled in terms of quality and adaptability, they are manufactured on-demand in order to reach your highest expectations.
Metal/Metal tightness by direct contact without jamming the butterfly ring on the seal, also known as "eccentric" butterfly valve
Tight closure security : the closing position is ensured directly by the metal Seat's contact on the disc metal ring
No friction from the first degree of opening for low wear out and improved longevity
A design with advantages
Better trade-off of mass, face-to-face and nominal diameter than other types of metal/metal valves (ball valves, gate valves, globe valves)
Optimized disc/shaft design to reach a high flow coefficient (low head loss)
Internal protection ring for bushing , preventing any particles from getting in
Intrinsic Fire safe Pressure (BS 6755 part 2, API607)
Mounting plate ISO 5211
Common applications
Steam
Thermal power plants
Sea water desalination
District heating
Oil
Petrochemistry
Cryogenics
Factories of transformation processing
