Series WVS
Valve Setters - Used with Watts
SilverEagle™ N-Shape Assemblies
Sizes: 3" - 10" (80 – 250mm)
The Watts Series WVS valve setters are designed to aug-
ment the installation of the "N" series backflow prevention
valves. The Series WVS are available in three connection
options, Flange by Flange, Mechanical Joint by Flange, and
Mechanical Joint by Mechanical Joint. They are constructed
of fusion epoxy coated ductile iron. Integral ductile iron sup-
port between elbows transfers thrust downstream, thus elimi-
nating thrust block requirements between elbows. Mechanical
joint restraint devices may be used at the pipe connections,
depending on local conditions.
