Description
CSB700 Series regulators are typically installed on industrial
and commercial applications. See Table 1 for Available
Configurations. Types under CSB700 Series are utilized
for high capacities. Low, Medium and High outlet pressure
constructions are available via Types CSB700, CSB720 and
CSB750 respectively, that provide outlet setpoints ranging
from 9.0 mbar to 4.0 bar / 0.13 to 58.0 psig.
The Types CSB704, CSB724 and CSB754 are examples of
CSB700 Series configurations that offer a slam-shut module
that shuts off the flow of gas to the downstream system in
the event of outlet pressure rising above or falling below the
predefined levels due to a failure.
Optional token relief is available, which acts as a low
capacity internal relief valve to relieve minor overpressure
situations due to nicks or other minor damage to the
orifice or disk or due to thermal expansion of the
downstream system.
External outlet pressure registration requires an external
control line/sense line.
