The CSB600 / CSB700 Series
direct‑operated, spring-loaded regulators
have been engineered to fit a multitude of
pressure-reducing applications including
commercial and industrial installations.
This flexibility is provided by the numerous
body sizes and end connections, outlet
pressure settings, as well as the option for
internal or external pressure registration.
In addition to application flexibility, the
CSB600 / CSB700 offer overpressure
protection options, which include an
integral slam-shut and also token relief
to meet your demands on application
The CSB600 / CSB700 Series are in
conformity with the Pressure Equipment
Directive PED 97/23/EC. The base
regulator is classified under Category I,
the regulator with slam-shut module is
classified under Category IV.
