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 300 psi (20.7 bar) at 300°F (150°C). Flanged (125#) and grooved connections are available for sizes 2 1 ⁄ 2 " – 12" (65mm – 300mm) 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 Gruvlok 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.
