  • Type:

    flat seat

  • Material:


  • Burst pressure:

    10 bar (145 psi)

  • Nominal diameter:

    Min.: 25 mm (1 in)

    Max.: 250 mm (10 in)


Three-part design consisting of a bursting membrane
made from DIABON graphite reinforced in
the mounting area and a two-part holder made
from stainless steel grade 1.4571 whose upper
section rests on the lower section when assembled.
This arrangement prevents distortion of the membrane.
Series DV bursting membranes can also be
employed in series D DIABON graphite holders. If
this is done, however, the prescribed torque values
should be observed.
Membrane: Synthetic resin-impregnated process
equipment graphite (DIABON NS1)
Holder: Stainless steel grade 1.4571.
 Simple assembly, as no attention needs be paid
to torque (with metal holder)
 Cost advantage, because holder can be reused
