Reliable® Model G Automatic Sprinklers

Product Description
The Reliable Model G Automatic Sprinkler utilizes the
center strut solder in compression principle of construc-
tion. The fusible alloy is captured in the cylinder of the =
solder capsule by a stainless steel ball. When the fusible
alloy melts, the ball moves into the cylinder allowing the �
cylinder to fall away from the sprinkler.When this happens, J; -
the lever is released to spring free from the sprinkler so rtsca-
that all of the operating parts clear from the waterway al-
lowing the deflector to distribute the discharging water.
Except for the parts in the cylinder as mentioned above, Upright Pendent
the sprinkler components are made from copper based
alloys for maximum corrosion protection.Lead plated,wax
coated or wax over lead plated sprinklers are available for .nr*
specially severe environments. Chrome plated sprinklers
are available for decorative purposes. , _'
All sprinklers are individually hydrostatically tested. All me
sprinklers are identified as to their fusing point by mark
ings that appear on several of the operating parts and by
an identifying color that appears on the frame.
