XXII. 2900-40 Series POSRV Options (Cont.)
L. Pressure Spike Snubber
Consolidated recommends the use of a pressure spike snubber
(Figure 55) 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.

(Shown with optional sensing ring)
M. Remote Pilot Mounting
The 39PV pilot 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
As standard, the pilot valve inlet is piped to a location remote
from the main valve. In this application, the customer pipes
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).
