Circuit Balancing Valves Pictorial Table of Contents
GRINNELL Model CB800 Circuit Balancing Valves are designed to achieve accurate and efficient balancing of hydronic heating or cooling systems . Circuit Balancing Valves provide superior accuracy in measuring flows rather than ball type circuit setters .
The CB800 valve serves 5 functions:
• Throttling
• Measuring differential pressure • Draining
• Filling
• Positive shutoff
These valves are rated at 2,068 kPa (300 psi) at 150°C (300°F) .
The valve is made of dezincification-resistant brass and bronze components . Threaded and solder connections are available for sizes 15mm – 50mm (1⁄2" – 2") sizes with bronze bodies . Flanged (125#) and grooved connections are available for sizes 65mm – 300mm (21⁄2" – 12") with cast iron bodies .
The Y-Pattern style provides low pressure drop . The globe
style valve allows for precise throttling . The easy-to-adjust digital/vernier handwheel provides a minimum of 70 unique handwheel positions . The handwheel and test ports are located on one side for easy access . A built-in memory stop ensures
the setting can be returned to a balanced position after shutoff . The self-sealing pressure/temperature test ports use standard insertion probes to eliminate additional components .
The GRINNELL Circuit Balancing Valve is installed with flow in the direction of the arrow, and may be in the horizontal or vertical position . The handwheel can be positioned up or down, or on either side .
