PED Conformity Statement and Information
The CSB700 Product Series is in conformity with the
Pressure Equipment Directive PED 2014/68/EU. Pressure
regulator does not require any supplementary upstream
safety accessory for protection against overpressure
compared with its design pressure PS, when upstream
reducing station is sized for a max downstream incidental
MIPd <= 1.1 PS.
PED Related Information
See Table 2
1. The pressure/temperature limits in this Instruction Manual or any applicable standard limitation should not be exceeded.
2. Standard token relief set values listed in Tables 8a, 8b, 8c and 8d are based on -20 to 60°C / -4 to 140°F.
3. Product has passed Emerson Process Management Regulator Technologies, Inc. (Emerson) testing for lockup, relief start-to-discharge and reseal down to -40°.

WARNING
Failure to follow these instructions or to
properly install and maintain this equipment
could result in an explosion and/or fire
causing property damage and personal
injury or death.
Fisher™ regulators must be installed, operated
and maintained in accordance with federal,
state and local codes, rules and regulations
and Emerson instructions.
If the regulator vents gas or a leak develops
in the system, service to the unit may be
required. Failure to correct trouble could
result in a hazardous condition.
Call a gas service person to service the
unit. Only a qualified person must install or
service the regulator.

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.

Table 8c. North American Overpressure and Underpressure Shut-o UPSO/OPSO Ranges
Table 8d. European Overpressure and Underpressure Shut-o UPSO/OPSO Ranges
Example: If a non-standard setpoint is needed, see the following example for the proper use of Tables 8a, 8b, 8c and 8d. In this
example, the non-standard regulator setpoint is 140 mbar / 2.0 psig. The minimum factory token relief set pressure is 130% of the
non-standard setpoint. The resulting token relief set pressure is 183 mbar / 2.6 psig. The minimum factory OPSO and UPSO set
pressures are 165% and 50% of the non-standard setpoint, respectively. The resulting minimum settings are: OPSO = 231 mbar /
3.4 psig and UPSO = 70 mbar / 1.0 psig.
