BLB 300 Orifice Plate with Carrier Ring 
Single Bore Pressure Taps

Construction

Carrier-ring with single bore acc. to DIN 19205 
And fixed orifice plate. This can be supplied as 
an orifice (ISO 5167), a cylindrical orifice, 
quarter circle nozzle or as a segmental orifice, 
double coned orifice, according to requirements. 
The orifice plate welded or screwed into the 
carrier-ring or the orifice can be machined as a 
single piece. When mild steel is used,
the bore is reinforced with stainless steel. When
unusual materials are specified, the orifice plate is
screwed onto the carrier ring.

Benefits

A compact and economical construction, with 
a limited installed length. The orifice plate is easy 
to clean and thus suitable for media that solidify 
or form deposits, or for a plan that is not in constant use.

Technical Details

Nominal pressure: PN 6 to PN 160 ( PN 150 Ibs to 1500(2500) Ibs

Nominal diameter: DN 50 ( 2") to DN 1600 (64" ) to PN 16 (150 Ibs)
DN 50 ( 2") to DN 500 (20") to PN 40 (900 Ibs)
DN 50 ( 2") to DN 350 (14") to PN 160 (1500 Ibs)
DN 50 ( 2") to DN 250 (10") to PN 320 (2500 Ibs)

Outer diameter: The outer diameter of the carrier-ring (with smooth
sealing surface) can be calculated by the bolt bore
diam. subtracting the bolt diam. of the pipe flanges.
Tongue/groove : d4 = the outer diameter of the
face + 10mm; Ring seal + 1 6mm

Installation length: 25mm, 40 mm, 65mm, other lengths are possible.

Bore-diameter: the calculation of this will made by us from the data
supplied, considering the relevant standards and
regulations.

Pressure loss: The remaining pressure loss = d2 : D2 and lies
between 30-80% of the different pressure, it is given 
in the data sheet.
