Note

This is the specification for connecting the remote seal to the lower housing, not the
torque specification for the lower housing onto the process flanged connection. The lower
housing bolts should be torqued to the applicable flange requirements.

3.6.1

4.1-in. (104 mm) diaphragm diameter option

The standard diaphragm size for the RFW remote flanged seal is 2.4-in. A larger, 4.1-in.
(104 mm), diaphragm size is offered for small spans to reduce temperature error when
taking process measurements.

3.6.2

Parts required for installation

The parts required to install the RFW remote flanged seal will be defined here. Prior to
installation, you will need the following:

•

Torque wrench

•

Mounting hardware (end-user-supplied)

•

Gasket (lower housing to process flange) (end-user-supplied)

•

Gasket (remote seal to lower housing) (Emerson-supplied)

Note

Typically, the stud bolt design includes Emerson-supplied stud bolts.

Verify the gasket material is appropriate for the application.

Inspect bolts to ensure the material is compatible with industry standards per the
application such as ASME PCC-1.

3.6.3

Standard design installation steps

It is recommended that two people install the standard design RFW remote flanged seal to
ensure proper alignment during installation.

Follow these steps to install the standard design RFW remote flanged seal on an existing
process flange:

Procedure

1. Remove the protective cover from the diaphragm of the remote seal. Use extreme

caution during installation to ensure the diaphragm is not damaged.
