MB & MBV
Monoblock Graphite Disks
Graphite disks especially suited for low pressure applications.
One-piece assembly and attached gaskets simplify installation and reduce down-time
Available sizes range from 0.5 to 24 inches (15 mm to 600mm)
Available temperatures range to 400 degrees Fahrenheit (205 degrees Celsius)
MonoBloc disks fit most applications where a graphite disk is needed.
When using a MonoBloc disk in application:
Vacuum supports are needed for disks rated below 22 psig (1.52 bar) and where a vacuum condition exists (Model MBV™)
Vacuum supports not needed for sizes 0.5", .75" (15 and 20 mm)
Temperature ranges -100 degrees Fahrenheit to 400 degrees Fahrenheit (-73 degrees Celsius to 205 degrees Celsius)
Armoring is recommended for all graphite disks for added safety, easier installation and elimination of breakage during installation
Armor reduces the possibility of a premature burst due to uneven or excessive torqueing of the flange studs
All MB™ disks supplied with integral gaskets
Available for installation between ANSI, DIN, AFNOR, BS and JIS pipe flanges & located inside the bolt circle
MB™ MonoBloc disks are available in sizes from 0.5" to 24" (15mm to 600mm) with a temperature range to 400ºF (205º C).

Type
AMB and AMBV (armored versions of types MB & MBV) share the above
dimensions.
Note: In
the case of the MBV disk either a dial type or a bar type vacuum support
is integrated into the disk. This will reduce the free vent area to
provide the following proportion of the internal
bone:
| Size | 1" | 1 1/2" | 2" | 3" | 4" | 6" | 8" | 10" and Larger |
| Dial Type | - | 0.56 | 0.57 | 0.60 | 0.62 | 0.58 | 0.60 | 0.60 |
| Bar Type | 0.7 | 0.80 | 0.80 | 0.80 | 0.80 | 0.80 | 0.80 | 0.80 |
Bar
type vacuum supports are recommended for set pressures between 10 psig
(0.69 bar) and 22 psig (1.52 bar).
Dial type vacuum supports are recommended for set pressures up to 10 psig (0.69 bar).
Where back pressure resistance exceeding 1 atmosphere is required, bar and dial supports can be used. Please consult BS&B
