The type B regulators provide
economical pressure reducing contrai in
a variety of residential, commercial and Use of 2, 3 or 4 regulators
industrial applications. The regulator can be used mounted parallel (battery)
for a variety of gaseous fluids. lt will be utilized in a
distribution network, with inlet pressure varying from 5 to
0, 1 bar. The outlet pressure can be set between 9 and 400
mbar, with a flow capacity of O to 48 m3/h. The regulator can
be installed in pressure reducing cabinets or reducing and
metering cabinets in a compact design above ground or in
underground modules.

e PRINCIPLE OF OPERATION
REGULATING
p
The pressure reduction is done in
two stages:
The first stage reduction is taken
over the inlet plug 10 and the seat
ring 11. Tightness is ensured
through the plug dise seat 10
which closes on the seat ring
11. Pressure regulation is
controlled by the 1 st
stage diaphragm 20,
which sen ses
intermediate pressure
on one side and on the
other side the set
pressure of the spring
21.
The second stage
reduction is taken over
the regulating plug 12
and the seat ring 13.
Pressure reduction is
controlled by the 2"d stage
diaphragm, which senses
outlet pressure on one side and
on the other the set pressure of 20 13
the spring 22. This spring is factory
pre-set. Finally on modules other than
the BCH, the trip set lever functions also
as trip lever, which closes the second stage regulating plug 12.

Pressure sensing is internai and the regulator does not
require external sensing lines.
Use the torque indicated on the inlet connection.
