triple offset
butterfly valve bv03

BV03

The IVALDISC BV03 model has two main functions :

1 - On/off valve :
• Bidirectional zero leaks according to API 598, EN12266-1​
• No retention area
• Intrinsic fire safe

2 - Regulation valve :

• Bidirectional zero leaks according to ANSI/FCI 70-2 Class VI

• High flow coefficient (Kv, CV)

• Important regulation coefficient

• Characteristic of exponential flow (equal percentage) and linear between 60 and 80 opening degrees

Triple-offset butterfly valve (BV03).

Design advantages :

• Metal/Metal tightness by direct press without jamming of the butterfly ring on the sea (butterfly valve said "eccentric")

• The closing position is ensured directly by the metal Seat's reaction on the disc metal ring (tight closure security)

• All contact points of the disc ring quit seat surface, at the same time, from the first degree of opening : No friction = No usury = longevity of use

• Better ratio mass-face-to-face / nominal diameter than other types of metal/metal valves (ball valves, gate valves, globe valves)

• Optimized disc/shaft design to obtain an important flow coefficient (low head loss)

• Internal protection ring for bushing , preventing any particles getting inside

• Intrinsic Fire safe Pressure (BS 6755 part 2, API607)

• Mounting plate ISO 5211

Performance :

• Temperature: from -200° to 750° C

• Pressure: up to 100 bar (more on request)

• Bidirectional zero leaks according to API 598, EN12266-1 and ANSI/FCI 70-2 Class VI regulation's 

Range :

• DN80-3200

• Flange PN10 to PN100

• Flange 150 600

• Types of body : wafer, lug, flanged, welded ends
