L. Pressure Spike Snubber
BHGE recommends the use of a pressure spike snubber
(Figure 78) for all applications which may have high
frequency pressure spikes. The pressure spike snubber
is designed to dampen the pressure spikes which could
cause unnecessary parts wear or premature valve
opening.
M. Remote Pilot Mounting
The 39PV and 39MV pilots can be mounted separately
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).

(Figure 79)
An option which allows the pilot valve inlet to be piped to
a location just below the inlet flange of the main
valve base.
