M. Remote Pilot Mounting
The 39PV and 39MV pilots can be mounted
sepaately from the main valve. Remote pilot
mounting will allow heating or cooling the pilot in
case ambient conditions are outside the scope of
the pilot. It will also enable the user to group several
pilots together for control of ambient conditions in
a smaller space. In addition, this promotes easier
maintenance.
N. Remote Sensing
The pilot valve inlet may be piped to a location
remote from the main valve. In this application,
the customer may pipe the inlet sensing line to
some location other than where the main valve is
located and where the pressure will be relieved (for
tubing size and maximum length, consult factory for
recommendations).
O. Sensing Ring Options
Integral sensing rings allow the pilot valve inlet to be
piped to a location just below the inlet flange of the
main valve base.
The 2900 Gen II "IS" (Figure 90) option is the
standard and recommended configuration for integral
sense when the remote sense option is not selected.
This integral sensing ring is a drop-in solution that
doesn't require piping modifications due to center-to-
face dimensional differences. Therefore it can be used
to replace existing API 526 Spring loaded PRVs.
The "SR" option (Figure 91) is also available for
existing 2900 installations only when the SR sensing
ring was used. Using this sensing ring to replace API
526 Spring Loaded PRVs will result in center-to-face
dimensional differences.
