P.E.D. Categories

This product may be used as a pressure accessory with

pressure equipment in the following Pressure Equipment

Directive. For information on the current PED revision see

Bulletin: D103053X012. 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 maximum

downstream incidental MIPd <= 1.1 PS.

Table 7c. North American Overpressure and Underpressure Shut-off UPSO/OPSO Ranges

Table 7d. European Overpressure and Underpressure Shut-off UPSO/OPSO Ranges

Example: If a non-standard setpoint is needed, see the following example for the proper use of Tables 7a, 7b, 7c and 7d. 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.

CSB700 Series

Downstream Control Line Installation

WARNING

Failure to install a downstream control line

could result in a hazardous condition. Install

downstream control line(s) to the slam-shut

device when construction uses external

pressure registration. The regulator and

slam-shut device will not control pressure

or shut off if a downstream control line is

not installed on those constructions where

external pressure registration is required.

CSB700 Series regulators with an “ET” or “EN” in the type

number use external pressure registration. To communicate

the downstream pressure to the regulator, connect a

downstream control line tubing to the 3/4 NPT control line

tapping in the lower diaphragm casing and connect the other

end of the tubing downstream of the regulator outlet with a

minimum distance of 6 times the outlet pipe diameter.

For all types with external control lines, use tubing with an

inner diameter of 16 mm / 0.63 in. or larger.

Downstream Control Line Installation with

Slam-Shut Device

Refer to Figure 1. When installing the Types CSB704ET,

CSB704FET, CSB704FEN CSB704EN, CSB724ET,

CSB724EN, CSB724FEN and CSB754EN regulators,

connect downstream control line tubing to the lower casing

of the regulator and run the tubing downstream of the

regulator outlet with a minimum distance of 6 times the outlet

pipe diameter. Connect a second, separate downstream

control line tubing to the lower casing of the slam-shut and

run the tubing downstream of the regulator outlet a minimum

distance of 6 times the outlet pipe diameter.

For all types with external control lines, use tubing with an

inner diameter of 16 mm / 0.63 in. or larger for the primary

regulator and 6.4 mm / 0.25 in. or larger for the slam-shut.

Installation with External Overpressure Protection

If the regulator is used in conjunction with a Type 289H

relief valve, it should be installed as shown in Figure 6.

The outside end of the vent line should be protected

with a rainproof assembly. The Type 289H is typically

set 25 mbar / 10 in. w.c. higher than the outlet pressure

setting of the regulator, up to 75 mbar / 30 in. w.c. outlet

pressure. For pressure greater than this, set the Type 289H

0.05 bar / 0.73 psi higher than the outlet pressure setting

of the regulator. Refer to the 289 Series Instruction Manual

(D100280X012) for more information.

Installation

WARNING

Only qualified personnel shall install or

service a regulator. Regulators should

be installed, operated and maintained

in accordance with international and

applicable codes and regulations and

Emerson instructions.

If the regulator vents fluid or a leak develops

in the system, it indicates that service

is required. Failure to take the regulator

out of service immediately may create a

hazardous condition.

Personal injury, equipment damage or

leakage due to escaping gas or bursting of

pressure containing parts may result if this

regulator is overpressured or is installed

where service conditions could exceed the

limits given in the Specifications section or

where conditions exceed any ratings of the

adjacent piping or piping connections.

To avoid such injury or damage, provide

pressure-relieving or pressure-limiting

devices (as required by the appropriate code,

regulation or standard) to prevent service

conditions from exceeding limits.

Additionally, physical damage to the

regulator could result in personal injury and

property damage due to escaping fluid. To

avoid such injury and damage, install the

regulator in a safe location.

Clean out all pipelines before installation of the regulator

and check to be sure the regulator has not been damaged

or has collected foreign material during shipping. For NPT

bodies, apply pipe compound to the external pipe threads.

For flanged bodies, use suitable line gaskets and approved

piping and bolting practices. Install the regulator in any

position desired, unless otherwise specified, but be sure flow

through the body is in the direction indicated by the arrow on

the body.

Note

It is important that the regulator be installed

so that the vent hole in the spring case

is unobstructed at all times. For outdoor

installations, the regulator should be located

away from vehicular traffic and positioned

so that water, ice and other foreign materials

cannot enter the spring case through the

vent. Avoid placing the regulator beneath

eaves or downspouts and be sure it is above

the probable snow level.

CSB700 Series

Vent Line Installation

CSB700 Series regulators have a 1 NPT screened vent

opening in the spring case. If necessary to vent escaping

gas away from the regulator, install a remote vent line in

the spring case tapping. Vent piping should be as short

and direct as possible with a minimum number of bends

and elbows. The remote vent line should have the largest

practical diameter. Vent piping on regulators with token relief

must be large enough to vent all relief valve discharge to

atmosphere without excessive backpressure and resulting

excessive pressure in the regulator.

For types with optional token relief, this low capacity relief

is located in the spring case of the primary regulator. If

necessary to vent escaping gas away, install a remote vent

line in the spring case tapping of the primary regulator as

described above. Periodically check all vent openings to be

sure that they are not plugged or obstructed.

For Types CSB700/CSB700F/CSB720/CSB720F, outlet

pressure higher than 0.34 bar / 5.0 psig above the setpoint

may damage internal metallic parts. For Type CSB750,

outlet pressure higher than 1.5 bar / 21.8 psig above the

setpoint may damage internal metallic parts.

Overpressure Protection

The recommended pressure limitations are stamped on

the regulator nameplate. Some type of overpressure

protection is needed if the actual inlet pressure exceeds the

maximum operating outlet pressure rating. Overpressure

protection should also be provided if the regulator inlet

pressure is greater than the safe working pressure of the

downstream equipment.

Regulator operation below the maximum pressure limitations

does not preclude the possibility of damage from external

sources or debris in the line. The regulator should be

inspected for damage after any overpressure condition.

Startup

The regulator is factory set at approximately the midpoint

of the spring range or the pressure requested, so an initial

adjustment may be required to give the desired results.

With proper installation completed and relief valves properly

adjusted, slowly open the upstream and downstream

shutoff valves.

Adjustment

Note

For types that include the slam-shut module,

refer to the instruction manual for Type VSX8

slam-shut for adjustment and maintenance

of the slam-shut.

To change the outlet pressure, loosen the hex nut and turn

the adjusting screw clockwise to increase outlet pressure or

counterclockwise to decrease it. Monitor the outlet pressure

with a test gauge during the adjustment. Tighten the hex nut

to maintain the desired setting.

Taking Out of Service (Shutdown)

WARNING

To avoid personal injury resulting from

sudden release of pressure, isolate

the regulator from all pressure before

attempting disassembly.
