Product Description
The Reliable Model G Automatic Sprinkler utilizes the
center strut solder in compression principle of
construction. 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, the lever is released to
spring free from the sprinkler so that all of the operating . .
parts clear from the waterway allowing the deflector to
distribute the discharging water.
Except for the parts in the cylinder as mentioned Upri ht Pendent
above, the sprinkler components are made from 9
copper based alloys for maximum corrosion
protection. Lead plated, wax coated or wax over lead
plated sprinklers are available for specially severe .
environments. Chrome plated sprinklers are available
for decorative purposes.
All sprinklers are individually hydrostatically tested. _
All sp rinklers are identified as to their fusing point by .
markings that appear on several of the operating parts
and by an identifying color that appears on the frame.
