The G15 Pressure Indicator can be used

nnnn

with our Sentry Rupture Disc Assembly,

nnnn

which helps prevent leakage of both Halocarbon

nnnn

and Ammonia refrigerants by indicating whether

nnnn

the relief valve has discharged.

nnnn

The Sentry Rupture Disc Assembly, as required

nnnn

by ANSI/ASME code, provides a chamber be-

nnnn

tween the rupture disc and the relief valve, and a

nnnn

connection to install the new Pressure Indicator.

nnnn

This arrangement permits a positive indication

nnnn

that the disc has ruptured and the relief valve

nnnn

has discharged.
