Bolt Torquing
When connecting the process and mating flange, the bolts should be torqued
to the applicable flange requirements. Required torque is a function of the
gasket material and surface treatment of the bolts and nuts which are
customer supplied.
Flushing Connection
Lower Housing
A lower housing or flushing connection is
always
required for the RFW type
seal.
Gasket Installation
When connecting the remote seal, gasket, and flushing connection ring make
sure the gasket is properly aligned on the gasket sealing surface. Failure to
properly install the gasket may cause process leaks, which can result in death
or serious injury.
4.1-in. (104 mm)
Diaphragm Diameter
Option
The largest standard diaphragm size for the RFW seal is 2.4-in. (61 mm). A
larger diaphragm option, 4.1-in (104mm), is offered which allows the RFW
seal more flexibility and reduces temperature error when taking process
measurements.
