Model CB800
Double Regulating and
Commissioning Valves
Available in Sizes ½ to 12 Inches
The Model CB800 Double Regulating and Commissioning
Valves offer features necessary to achieve accurate and
efficient balancing of hydronic heating or cooling systems.
One valve series performs five functions: throttling,
measuring (pressure and temperature), positive shutoff,
draining, and filling.
The Y pattern provides minimum pressure drop across
the valve. The CB800 globe style design ensures precise
throttling. Both the hand-wheel and test ports are located
on the same side for easy access. The digital/vernier
hand-wheel may be reoriented a minimum of 70
unique positions to allow for accuracy. The hand-wheel
lock feature prevents unauthorized hand-wheel
movement. A built-in memory stop ensures return
to the balanced position after shutoff.
Additional Features
•Double Regulating and Commissioning Valves provide
superior accuracy in measuring flows, rather than ball
type circuit setters
•The Double Regulating and Commissioning Valve
is installed with flow in the direction of the arrow,
and may be in the horizontal or vertical position.
The hand-wheel can be positioned up or down, or
on either side
•Backed by the industry’s best 10-Year Limited
Warranty
