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 _ a
cylinder of the solder capsule by a stainless steel ball. '1, ' `` '.
When the fusible alloy melts, the ball moves into the U . _
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 - r.
parts clear from the waterway allowing the deflector to
distribute the discharging water. . • .
IF -
Except for the parts in the cylinder as mentioned
above, the sprinkler components are made from Upright Pendent
copper based alloys for maximum corrosion ,
protection. Lead plated, wax coated or wax over lead =
plated sprinklers are available for specially severe ` t
environments. Chrome plated sprinklers are available ,
for decorative purposes.
All sprinklers are individually hydrostatically tested.
All sprinklers are identified as to their fusing point by " t•
markings that appear on several of the operating parts
and by an identifying color that appears on the frame.
