CSB400 Series

Figure 8. Type CSB400 “Series Monitor” Regulator Downstream Control Line Installation

Before installing the regulator, check for

damage which might have occurred in

shipment. Also check for dirt or foreign

matter which may have accumulated in

the regulator body or in the pipeline. Apply

pipe compound to the external threads of

the pipeline and install the regulator so that

ow is in the direction of the arrow cast on

the body. The diaphragm casing assembly

can be rotated to any position relative to the

body. Loosen the two cap screws (key 71,

Figure 11) in order to rotate the diaphragm

casing assembly.

General Installation Instructions

Before installing the regulator,

• Check for damage, which might have occurred

during shipment.

• Check for and remove any dirt or foreign material, which

may have accumulated in the regulator body.

• Blow out any debris, dirt or copper sulfate in the copper

tubing and the pipeline.

• Apply pipe compound to the external threads of the pipe

before installing the regulator.

• Make sure gas ow through the regulator is in the same

direction as the arrow on the body. “Inlet” and “Outlet”

connections are clearly marked.

• Verify that:

- Equipment limits of utilization (PS, TS) corresponds

to the desired operating conditions.

- The inlet is protected by an appropriate device(s) to

avoid exceeding the allowable limits (PS, TS).

• When designing a pressure reducing station using

a CSB regulator, make an analysis if it is necessary

to take into account the effects of wind, snow

and temperature to avoid unnecessary load and

movement to the anges of the equipment.

• If needed, a support may be used under the piping

and regulator/slam-shut body to avoid excessive

pressure force on the regulator/slam shut.
